1. Introduction

Welcome to VERSAMAP! VERSAMAP is a versatile mapping program which
can transform spherical latitude, longitude values into planar x,y
map coordinates and plot them on a map projection of your choice.
VERSAMAP can print the resulting map on the screen, on dot matrix or
laser printers, and as .PCX, .PIC, or ASCII files for use with paint
programs, word processors, and presentation or technical graphics
programs.

The VERSAMAP disk(s) should contain the following files:

VMAPREAD.ME -- how to get started
VMAP.DOC -- instruction manual using only standard ASCII
characters. Print this if your printer will
not print the IBM block graphics characters.
VMAP_EXT.DOC -- instruction manual using IBM extended
character set. Print this if your printer
will print the IBM block graphics characters.
VMAP.EXE -- the mapping program
VMAP.MAP -- digital map of the world (14,000 points)
VMAPFAST.MAP -- small digital world map (3,000 points). Use
this map if VMAP.MAP plots too slowly on your
computer.
VMAPUSER.PRN -- sample file in user supplied data record
format. Use this input file to study the
different symbols that can be plotted.
VMAP_FIX.MPS -- a small file used to concatenate World
Digitized binary map files
VMAP_FIX.MP1 -- a small file used to concatenate World
Digitized ASCII map files.
REGISTER.DOC -- registration form
MSHERC.COM -- driver for Hercules mono graphics

Please make backup copies of these files before running the program.


2. Computer Requirements for Running VERSAMAP

MS-DOS 3.0 or higher;
CGA, MCGA, EGA, or VGA video display adapter and
color monitor, or Hercules mono graphics and
monochrome monitor;
512K memory;
a dot matrix or laser printer is optional;
a Microsoft compatible mouse is optional;
a math coprocessor is not required but VERSAMAP will run
several times faster if one is installed.

4. Registration

Shareware distribution gives users a chance to try software before
buying it. VERSAMAP is a "shareware program" and is provided at no
charge to the user for evaluation. If you find this program useful
and find that you continue to use VERSAMAP after a reasonable trial
period, you must register the program. The registration fee will
license one copy for use on any one computer at any one time. You
must treat this software just like a book. An example is that this
software may be used by any number of people and may be freely moved
from one computer location to another, so long as there is no
possibility of it being used at one location while it's being used
at another. Just as a book cannot be read by two different persons
at the same time.

Registration of the program is $15, for which you will receive a
copy of the most recent version of the program plus 2 additional
digital map files, MWDB5.ALL (4,000 points) and MWDB3.ALL (26,000
points). Registration entitles you to mail and telephone support
concerning problems you encounter with VERSAMAP. A registration
form is included in the file REGISTER.DOC, and also on page 26 of
this manual. Please make payment in U.S. currency. Persons living
outside the United States can register VERSAMAP by obtaining a
Postal Money Order payable in U.S. dollars from their National Post
Office.

The registration form includes space for comments about the program.
I would appreciate your comments about VERSAMAP even if you do not
register your copy.

You are encouraged to share a copy of VERSAMAP with your friends for
evaluation. Please encourage them to register their copy if they
find it useful.

Anyone distributing VERSAMAP for any kind of remuneration must first
contact Charles Culberson at the address on the registration form
for authorization. This authorization will be automatically granted
to distributors recognized by the Association of Shareware
Professionals as adhering to its guidelines for shareware
distributors, and such distributors may begin offering VERSAMAP
immediately. However Charles Culberson must still be advised so
that the distributor can be kept up-to-date with the latest version
of VERSAMAP.

5. Plotting the Default World Map

Before reading the rest of the manual, let's plot a map of the world
on the screen. This will familiarize you with the operation of
VERSAMAP. The rest of the manual should make more sense once you
have actually used VERSAMAP.

VERSAMAP has built in defaults which plot a world map, from 80øN to
80øS latitude, and from 180øW to 180øE longitude, on a Mercator
projection. The default settings will not print any files to disk.

To run VERSAMAP with the default settings:

1. place the VERSAMAP disk containing the files,
VMAP.EXE and VMAP.MAP, in your disk drive
2. change to that drive
3. type VMAP
4. press the Enter key.

A screen with a menu bar across the top will appear once the program
has loaded. The pull-down menus are selected by pressing the Alt
key, followed by the highlighted letter of the desired menu; or by
pointing and clicking the left mouse button.

To plot the world map:

1. press the Alt key, to access the menus
2. press R, to select Run menu
3. press Enter, to select Go and begin the plot.

To plot the default map, the map file, VMAP.MAP, must be in the
current directory.

When the map begins plotting, the top line of the screen will
display (1) the name of the map input file being read, VMAP.MAP in
this case; (2) a reminder that pressing the Esc key will terminate
plotting and return you to the menu bar; and (3) the number of
points which have been plotted.



VMAP_EXT.DOC version 1.10 Page 4





The menu bar will reappear when the map is finished plotting. The
default map takes 52 seconds to plot on a 16MHz 386SX computer
equipped with a math coprocessor; it takes 19 minutes to plot on an
original 5MHz IBM PC without a math coprocessor.

To exit the program and return to DOS:

1. press the Alt key, to access the menus;
2. press P, to select the Projection menu;
3. press X from the Projection menu to exit the program.

Pressing the Esc key halts program execution and returns you to the
menu bar. Pressing Esc will not exit the program.

Please read the rest of the instruction manual before attempting to
plot maps which do not use the default parameters.

If VMAP.MAP plots too slowly on your computer, try using the map
file VMAPFAST.MAP. This file contains only 3,000 points. It takes
11 seconds to plot on a 16MHz 386SX computer, and 4.3 minutes on a
5Mz IBM PC.


6. Finding your Way with Latitude and Longitude

To use this program you should be familiar with the concepts of
latitude and longitude.

Latitude is the angular distance (in degrees) of a point on the
earth's surface north or south of the equator. The maximum values
of latitude are 90øN (north pole) and 90øS (south pole). The
equator is 0øN/S latitude.

Longitude is the angular distance (in degrees) of a point on the
earth's surface east or west of the meridian that passes through
Greenwich, England. The maximum values of longitude are 180øW and
180øE (the international date line). The meridian passing through
Greenwich is 0øE/W longitude.

Latitude and longitude values in VERSAMAP are entered as degrees,
minutes, seconds. There are 60 seconds in 1 minute, and 60 minutes
in 1 degree. One minute of latitude is equal to 1 nautical mile (1
nautical mile = 6076 feet = 1.852 kilometers = 1.1508 statute
miles).

If you are unfamiliar with the use of latitude and longitude to
locate points on the surface of the earth, please consult an
encyclopedia or an atlas.

A easily understandable introduction to the theory of map
projections is the book:

Porter W. McDonnell. 1979. Introduction to Map Projections.
Marcel Dekker, New York.

VMAP_EXT.DOC version 1.10 Page 5





A detailed discussion of the map projections used in this program,
showing actual plots, is given in:

John P. Snyder and Philip M. Voxland. 1989. An Album of Map
Projections. U.S. Geological Survey Professional Paper 1453.
U.S. Government Printing Office. 249 pages. $14.


7. Keys with Special Functions in VERSAMAP

Esc

Pressing the Esc key halts program execution and returns you to the
menu bar. Pressing Esc will not exit the program.

If you are in the process of plotting or printing a map, the program
checks the Esc key each time the record number or point, shown in
the upper right corner of the screen, is updated. Consequently, the
program may take a few seconds to respond after Esc is pressed.

There is one situation in which pressing Esc will not return you to
the menu bar. If you are in the LATITUDE AND LONGITUDE LIMITS or
SELECTION OF STANDARD PARALLELS windows, and have entered an
incorrect latitude or longitude value, VERSAMAP will issue an error
message and force you to enter a correct value before you can leave
the window.

Alt

Pull-down menus are selected by pressing the Alt key, followed by
the highlighted letter of the desired menu. Individual menu items
are selected by pressing the highlighted letter of each item; by
moving through the menu with the up or down cursor keys, and then
pressing Enter to select the item; or by moving the mouse cursor
over the desired item and pressing the left mouse button.

Exit the program

To exit the program and return to DOS:

1. press the Alt key, to access the menus;
2. press P, to select the Projection menu;
3. press X from the Projection menu to exit the program.

If a window is on the screen or a map is in the process of being
drawn, you must press Esc before you can access the menus and exit
the program.

Using a mouse

Most VERSAMAP features can be accessed by pointing and clicking the
left mouse button. The only cases in which a mouse cannot be used
are those requiring numerical or alphabetical input: such as the
latitude/longitude boundaries of the map, or filename input.

VMAP_EXT.DOC version 1.10 Page 6





Windows and pull down menus can be closed by clicking the left mouse
button when the mouse cursor is outside the window or menu box.


Moving around windows

The windows which pop up when menu selections are made contain
several types of items: (1) input fields; (2) vertical list boxes;
and (3) pushbuttons.

Input fields allow numeric and alphabetic input into the program.
An example of a window with numeric input fields is the LATITUDE AND
LONGITUDE LIMITS window selected by pressing Alt, then G, then M.
You can move within an input field with the right, left, Home, and
End cursor keys. To enter data into an input field, type the
correct characters from the keyboard. To exit an input field you
must press Enter.

Vertical list boxes allow one or more items in a list to be chosen.
Move through the list with the up and down cursor keys, and select
the correct item(s) by pressing the Space Bar or Enter. The item(s)
selected will be highlighted or indicated with a checkmark. If the
number of items in the list is too large to fit inside the box, a
scroll bar will appear along the right side of the box, allowing all
items to be viewed.

Pushbuttons, indicated by text inside brackets, such as < OK >,
allow the user to control program execution. The text inside the
brackets indicates the action to be taken when the pushbutton is
selected. The brackets of the currently active pushbutton are
highlighted, and its text is shown in all capital letters. To
select a pushbutton, tab to that button and press Enter.

Use the Tab key to move between items when more than one list box or
pushbutton occur in a window.


8. Running VERSAMAP

VERSAMAP Defaults

Each map projection in VERSAMAP has built in latitude/longitude
defaults which are active the first time you access the projection
during each session with VERSAMAP. These defaults allow you to plot
maps using each map projection without getting error messages. The
defaults are only active the first time you access a particular map
projection. For instance, if you access the Mercator projection,
then the Equirectangular projection, and finally return to the
Mercator projection, the latitude limits of the grid will be those
of the previous Equirectangular projection, 90øN/S, and you will get
an error message if you attempt to plot a Mercator projection
without changing the graticule.



VMAP_EXT.DOC version 1.10 Page 7





VERSAMAP Pull-down Menus

The following paragraphs provide a detailed discussion of each
VERSAMAP pull-down menu. For your first experience with VERSAMAP
you should run the program with its default settings (see Section 5
above).

When VERSAMAP is started, the following menu bar appears at the top
of the screen.

ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

When you begin plotting a map, by selecting the Go option in the Run
menu, the menu bar is replaced by the following line. This line is
not a menu bar, it is for your information only.

ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

While a map is plotting, the top line of the screen displays (1) the
name of the current map input file; (2) a reminder that pressing the
Esc key will terminate plotting and return you to the menu bar; and
(3) the number of points which have been plotted.

Once the map is completed, the menu bar reappears on the top line.

This menu lists the map projections on which you can plot your map.
The Gnomonic and Lambert azimuthal equal-area projections allow you

to plot your data in polar or equatorial aspects.


VMAP_EXT.DOC version 1.10 Page 8





Mercator

On this projection, meridians and parallels are parallel lines
perpendicular to each other. Meridians are equally spaced,
parallels are unequally spaced. The north and south poles cannot be
plotted because they project to infinity.

The scale is true along the equator, or along two parallels
equidistant from the equator. Since the scale increases rapidly
away from the equator, the areas of polar regions are greatly
exaggerated compared to those of equatorial regions.

The Mercator projection is commonly used for maps of the world, and
is designed so that straight lines on the map are rhumb lines (lines
of constant compass bearing). This is a useful property in
navigation and many nautical charts use Mercator projections.


Equirectangular

Meridians and parallels are equally spaced parallel lines
perpendicular to each other. The scale is true along the two
standard parallels and along all meridians. The scale along
parallels is too small between the equator and the standard
parallels, and too large between the standard parallels and the
poles.

The map can be visualized as projected on a cylinder which
intersects the globe at two standard parallels equidistant from the
equator. VERSAMAP allows the user to select the latitude of the
standard parallels.

The fact that meridians and parallels are equally spaced makes
interpolation easy. The projection is useful for maps of small
regions, since distortion is not large if one of the standard
parallels is chosen to bisect the region under consideration.


Equidistant Conic

Meridians are equally spaced lines converging at a point beyond one
of the poles. Parallels are equally spaced circular arcs centered
on the point where the meridians converge. The poles are circular
arcs of infinite scale. Distortion on the projection is
intermediate between that of equal-area and conformal conic
projections.

The scale is true along meridians and along two standard parallels.
VERSAMAP allows the user to select the latitudes of the standard
parallels.





VMAP_EXT.DOC version 1.10 Page 9





Lambert Conformal Conic

Meridians are equally spaced lines converging at a point, which is
one of the poles. Parallels are unequally spaced circular arcs
centered on the point where the meridians converge. The pole
opposite the point of convergence cannot be shown.

The scale is true along two standard parallels, which VERSAMAP
allows the user to select. The projection in conformal: the scale
is the same in all directions at a given point.


Albers Equal-Area Conic

Meridians are equally spaced lines converging at a point beyond one
of the poles. Parallels are unequally spaced circular arcs centered
on the point where the meridians converge. The poles are shown as
circular arcs of infinite scale.

The scale is true along two standard parallels, which VERSAMAP
allows the user to select. Since the projection is equal area, the
scale at any point on a meridian is the reciprocal of the scale
along a parallel at that point.


Gnomonic

The primary feature of gnomonic projections is that great circles
plot as straight lines. Thus the shortest distance between two
points on this map is the straight line connecting them.

VERSAMAP allows the user to select either the POLAR or EQUATORIAL
aspect of this projection.

In the polar aspect, meridians are equally spaced straight lines
converging at the pole. Parallels are unequally spaced circles
centered on the pole. The equator and the opposite pole cannot be
shown.

In the equatorial aspect, meridians are unequally spaced parallel
lines. Only meridians within 90 degrees of the central meridian can
be shown. The equator is a straight line; other parallels are arcs
concave toward the nearest pole. The poles cannot be shown.

To allow more detail to be shown, VERSAMAP truncates the cusps of
the equatorial gnomonic projection, and plots the map in the form of
a rectangle. For maps which span the equator, the maximum and
minimum latitudes of the grid are represented by points on the
central meridian at the top and bottom margins of the plot. For
maps which lie north of the equator, the maximum latitude is
represented by a single point on the central meridian at the top of
the plot. For maps lying south of the equator, the minimum latitude
is represented by a single point on the central meridian at the
bottom of the plot.

VMAP_EXT.DOC version 1.10 Page 10





The scale of the projection is only correct where the central
parallel crosses the central meridian.


Lambert Azimuthal Equal-Area

VERSAMAP allows the user to select either the POLAR or EQUATORIAL
aspect of this projection.

In the polar aspect, meridians are equally spaced straight lines
converging at one of the poles. Parallels are unequally spaced
circles centered on the pole. The opposite pole is a circle.

In the equatorial aspect, the central meridian is a straight line.
Other meridians are curves concave to the central meridian and
intersecting at the poles. The equator is a straight line; other
parallels are arcs concave toward the nearest pole. VERSAMAP
requires that the range of longitude for the equatorial aspect of
this projection be no greater than 180 degrees (one hemisphere).

The scale of the projection is only correct at the center of the
projection.



Hammer (-Aitoff) Equal-Area

This projection is useful for equal area maps of the entire world.

The central meridian is a straight line. Other meridians are curves
concave to the central meridian and intersecting at the poles. The
equator is a straight line; other parallels are arcs concave toward
the nearest pole.

The scale of the projection is only correct along the equator and
the central meridian.

This menu allows you to define the boundaries of the map; to select
the standard parallels, if any; to define the type of grid
superimposed upon the map; and to select the geographic features
(shorelines, islands, rivers, political boundaries) that you wish to
plot.

VMAP_EXT.DOC version 1.10 Page 11





Map Boundaries

After selecting this item, a window appears in which the latitude
and longitude limits of the map projection are entered. Data
entered on this screen define the area to be plotted, and the
spacing of latitude and longitude grid marks on the finished map.
Once you have completed the entire screen, the program checks for
errors in the latitude/longitude limits of your map projection, and
for errors in grid spacing. If the program detects an error it
prints an error message on the screen and requires you to correct
the mistake.

For instance, the program will not allow a Mercator projection to be
plotted if the Northernmost latitude is 90øN (north pole) or if the
Southernmost latitude is 90øS (south pole). Try entering 90øN as
the Northernmost latitude limit for a Mercator projection. In this
case, an error message will appear telling you to edit the data.

VERSAMAP requires that the grid spacing you select yield equally
spaced divisions between the northern- and southernmost latitudes,
and between the western- and easternmost longitudes. You will get
an error message, requiring you to edit the data, if the DEGREES
BETWEEN GRID MARKS that you have chosen does not yield equally
spaced divisions along the axes.

If you get an error message, you must correct the error before you
can leave the window!


Standard Parallels

After selecting this item, a window appears in which the latitudes
of the standard parallels are entered.

Conic Map Projections:

The conic projections in this program (equidistant conic, Lambert
conformal conic, Albers equal-area) require that you select 2
standard parallels of latitude. The scale of the map is true along
the standard parallels; the spacing of the parallels determines the
angle between meridians on the map.

There are 2 constraints on selection of the standard parallels:

1. they must lie between the northern- and southernmost
latitudes of your grid; and

2. they cannot be symmetrical about the equator. Standard
parallels at 20øN and 20øS are not allowed.


The program places default values for the standard parallels at 1/6
and 5/6 of the distance between the northern- and southernmost
latitudes of the grid.

VMAP_EXT.DOC version 1.10 Page 12





When this screen appears, the cursor will be in the first position
of the degrees column of the northernmost standard parallel. If the
default values are acceptable, press Esc to continue.

To change the values, enter a new value in the column being edited
and press Enter. The cursor will skip to the next column. Enter a
new value if desired and press Enter. Continue until you have
edited the last value. When you press enter in the last column (the
seconds column of the southernmost standard parallel), you will have
the option of re-editing the screen.

If you attempt to enter standard parallels which are equally spaced
about the equator, the program will print an error message and force
you to change the latitude of one or both of the parallels.


Equirectangular Map Projection:

This projection requires 2 standard parallels at equal distances
north and south of the equator. You may only select the northern
standard parallel. The other parallel is automatically placed in
the southern hemisphere at an equal distance from the equator.

The program places default values for the standard parallels at 1/2
the distance between the northern- and southernmost latitudes of the
grid if the northern- and southernmost latitudes lie in the same
hemisphere. If the northern- and southernmost latitudes of the grid
lie in opposite hemispheres, then the standard parallels are placed
at 1/2 the distance between the equator and whichever of the
northern- or southernmost latitudes of the grid lies closest to a
pole.

When this screen appears, the cursor will be in the first position
of the degrees column of the northernmost standard parallel. If the
default values are acceptable, press Esc to continue.

To change the values, enter a new value in the column being edited
and press Enter. The cursor will skip to the next column. Enter a
new value if desired and press Enter. Continue until you have
edited the last value. When you press enter in the last column (the
seconds column of the northernmost standard parallel), you will have
the option of re-editing the screen.


Graticule Type

This window allows you to select the type of grid that you wish
superimposed on your map. You have several choices, including
plotting the graticule as points, or with the points connected by
lines. The last menu item will plot your map without any latitude
and longitude markings whatsoever.




VMAP_EXT.DOC version 1.10 Page 13





To get a quick view of the appearance of the different grid choices,
select a grid type and then enter a null string (i.e. no file
specification) for the map input file path name. In this case, the
program will plot the graticule, but no map, on the screen.


Geographic Features

After selecting this item, a window appears which contains a list of
geographic features (coastlines, islands, lakes, rivers, countries,
states) which can be plotted by VERSAMAP. Move through the vertical
list with the up and down cursor keys, and toggle the features on or
off with the space bar. Checkmarked features will be plotted. The
defaults plot all features. Move to Proceed and press Enter to exit
the window.

Geographic features can only be plotted using input files from the
Micro World Data Bank II database. The map files supplied with
VERSAMAP come from Micro World Data Bank II and can be used to plot
different features. Geographic features cannot be plotted using map
files from other digital map databases, such as the World Digitized.

the contents of any disk directory, and to print the map on dot
matrix and laser printers.


Map Input Filenames

After selecting this item, a window appears in which the names of
the input boundary files are entered.

Up to 9 map boundary input filenames may be entered. The map
boundary input files are the files which contain the
latitude/longitude coordinates that you wish plotted on your map.

VMAP_EXT.DOC version 1.10 Page 14





The default file name for the first input file is VMAP.MAP in the
current directory. VMAP.MAP is the world map included on the
VERSAMAP disk. The default file names of the remaining 8 map input
files are null strings (i.e. no file name).

When the window is first displayed, the cursor is located at the end
of the first input file name. Type in the correct path name and
press Enter to accept the path name.


Symbol type, color, and size:

Once you enter a filename, a second window will appear which allows
you to specify the symbol used to plot the points in that file.

The symbol type determines whether your data is plotted as lines, as
individual points, or as crosses, squares, diamonds, or triangles.
If you select the symbol type Line, all points on a particular line
segment will be connected by straight lines. This is the default
symbol type for all files.

The other symbol types (Point, Cross, Square, Diamond, and Triangle)
allow you to superimpose individual latitude/longitude points on a
map created from a digital map database.

If you have a color monitor, VERSAMAP allows you to chose the color
of the symbols used to plot each file.

In addition, you may chose the size of the crosses, squares,
diamonds, and triangles used to plot your data. The size that you
enter is the radius of the symbol in pixels. The maximum size is 99
pixels. Size has no effect on the Line and Point symbol types,
these two types are always 1 pixel wide.

Once you have entered the symbol type, color, and size for the first
input file, tab to the < ok > button and press Enter. The window
disappears, and you are prompted for the name of the second map
input file (if any). If you wish to input a second map boundary
file, type its name and press Enter. Continue until you have
entered all of your map input files.

Once you have entered the symbol type of the last map input file
that you wish plotted, press Enter on < ok > to move to the next
filename. Erase the current path and then press Enter again.
Entering a null filename stops further input of map boundary input
files.

The program does not require any input map boundary files. If you
do not wish to input data, erase the default path name of the first
input file and press Enter. In this case, only the map graticule
(if any) will be plotted on the screen.




VMAP_EXT.DOC version 1.10 Page 15





VERSAMAP will accept map boundary input files from the following
public domain, shareware, and commercial digital map databases:
World Data Bank I, Micro World Data Bank II, The World Digitized,
and Cartog. In addition, VERSAMAP will accept input in an ASCII
text format. Section 9 contains a detailed discussion of the
various map databases that VERSAMAP recognizes.

VERSAMAP recognizes the various databases by their file name
extensions. The file names that you enter on this screen must have
one of the extensions given in Section 9. However, the names that
you enter can have different extensions. For instance, your first
file name could be from the CARTOG database with the extension BIN,
your second file name could be from the WORLD DIGITIZED database
with the extension MPS, and your third file name could be from the
MICRO WORLD DATA BANK II database, with the extension, ALL.


Report Map Parameters

The Versamap parameter report lists various information about the
map: the projection type; the grid type; the latitude/longitude
limits of the map; the maximum/minimum values of the transformed x,y
map coordinates; scale and area errors at selected points on the
map; and the names of the map input files.

The X-axis Length and Y-axis Length, listed under Relative Length of
Axes, are used to scale maps produced by exporting the map output
and map grid files to technical and business graphics programs. The
use of these two parameters is described in Section 10.

Use the up, down, Home, and End keys to scroll through the report.
Press F1 to print the report, Esc to return to menu bar.


View Disk Directory

This window allows you to view the contents of any disk and
directory. Disk drives are indicated by the letters to the
right of the drive letter. To select a disk drive, move the
highlight bar over the drive letter and press Enter. Directories
are indicated by the letters to the right of the directory
name. To select a directory, move the highlight bar over the
directory and press Enter.

The files in the directory are listed after the last directory
listing.









VMAP_EXT.DOC version 1.10 Page 16





Print Map

Selecting 'Print Map' allows you to define the dimensions and page
placement of the printed map. When you select this item, a window
titled 'MAP PLACEMENT ON PAGE IN INCHES' appears.

The default settings place the map in the center of the page, and
set the largest dimension (width or height) at 6 inches. The width
and height of the printed map are not independent. If you adjust
one dimension, the program automatically fixes the other. Maps will
be printed without any descriptive text, such as latitude or
longitude numbers. The grid spacing, and other information about
the printed map, can be obtained from the Report Map Parameters
option in the Input/Output menu. The menu bar will not be shown on
the printed map.


Define Printer

Before you print a map, you must select the type of printer which
will print the map. When you select 'Define Printer', a window
titled 'SELECT PRINTER TYPE AND PORT' appears. You may select one
of three printer types: Epson 9- or 24-pin dot matrix, or Hewlett-
Packard LaserJet II. If your printer is not compatible with one of
these printers, select None.

You may also select the printer port. Lpt1 is the default.


Save as PCX

Before saving the map as a bit-mapped .PCX paint file, you must
specify the filename and path of the file. After selecting this
item, a window titled 'SELECT .PCX FILENAME' appears. Type in the
correct filename and press Enter. Since the .PCX file will be
written immediately after you press Enter, the map you wish to save
must be displayed on the screen. The menu bar is not saved as part
of the file.

Maps on EGA and VGA monitors will be exported as white lines on a
blue background, just as they are displayed on the VERSAMAP screen.
When you print these maps from within a paint program, you may want
to print them as black lines on a white background. You can do this
by using the color eraser tool of your paint program to change the
white VERSAMAP lines to black, and to change the blue background to
white.

Maps will be exported without any descriptive text, such as latitude
or longitude numbers. The grid spacing, and other information about
the exported map, can be obtained from the Report Map Parameters
option in the Input/Output menu.

PCX files produced by VERSAMAP have been successfully imported into
Microsoft Paintbrush and PC Paintbrush IV Plus.

VMAP_EXT.DOC version 1.10 Page 17





Save as PIC

Before saving the map as a vector based Lotus .PIC graphics file,
you must specify the filename and path of the file. After selecting
this item, a window titled 'SELECT .PIC FILENAME' appears. Type in
the correct filename and press Enter. Since the .PIC file is
written as the map is being plotted on the screen, you must select
the .PIC filename before you plot the map. The menu bar is not
saved as part of the file.

Maps will be exported without any descriptive text, such as latitude
or longitude numbers. The grid spacing, and other information about
the exported map, can be obtained from the Report Map Parameters
option in the Input/Output menu.

PIC files produced by VERSAMAP have been successfully imported into
WordPerfect version 5.1, DrawPerfect, and Freelance Plus versions
2.0 and 3.0. Many PIC files produced by VERSAMAP are too large to
import into Freelance, since Freelance will not import PIC files
larger than 42K bytes.


Map Output Filenames

After selecting this item, a window appears in which the names of
any ASCII output files that you wish to write to disk are entered.

VERSAMAP will transform the latitude/longitude coordinates from the
map boundary input files into planar x,y map coordinates and output
them to disk in ASCII format. These output files can be imported
into graphics programs for the production of publication quality
maps. The use of the ASCII output map files in graphics programs is
discussed in Section 10.

The program will output up to 9 files, one for each of the map
boundary input files. You may choose any path names for these
files.

Output files are not required by VERSAMAP. If you do not want to
print a particular output file to disk, erase any characters in the
file name, and press Enter.

To enter an output file name, simply type in the path name and press
Enter. The cursor will then move to the next output file name.

Each output file corresponds to the input file of the same number.
For instance, if you have 5 input files, the fifth output file will
contain the transformed latitude/longitude coordinates from the
fifth input file.

If you decide to print a particular output file, you do not need to
print the output files corresponding to the other input files. For
instance, if you have 3 input files, you can print the output files
corresponding to the first and third input files, but not the second

VMAP_EXT.DOC version 1.10 Page 18





input file. Input a null string for any output file that you do not
want to print to disk (i.e. erase any characters in the file
specification and press Enter).

Data records in the ASCII map output files have the following
format.

X coordinate | space (ASCII 32) | Y coordinate |
carriage return (ASCII 13) | line feed (ASCII 10)

Data in most digital map databases is organized as line segments;
each line segment corresponds to a series of points which can be
connected by straight lines. In the map output files, the beginning
of each new line segment is indicated by a dummy point in which the
x coordinate is equal to 5.000000 (5 times the maximum x coordinate
of 1.000000) and the y coordinate is 5 times the maximum y
coordinate. In a map output file, any point with an x coordinate of
5.000000 is a dummy point which indicates the beginning of a new
line segment, and which will plot outside the boundaries of the map.


Grid Output Filenames

After selecting this item, a window appears in which the names of
any ASCII output graticule files that you wish to write to disk are
entered.

VERSAMAP will transform the latitude/longitude coordinates of the
grid type that you have selected into planar x,y map coordinates and
output them to disk in ASCII format. These output grid files can be
imported into graphics programs for the production of publication
quality maps. The use of ASCII output grid files in graphics
programs is discussed in Section 10.

The program will output 1 or 2 grid files, depending on the
graticule type that you chose. You may choose any path names for
these files.

Output grid files are not required by VERSAMAP. If you do not want
to print a particular grid file to disk, erase any characters in the
file name, and press Enter.

To enter a grid file name, simply type in the path name and press
Enter. The cursor will then move to the second grid file name (if
there is one), or to the next screen.

In most cases, a single grid file will be written to disk. The only
exception, the OUTSIDE BOUNDARY PLUS INTERIOR POINTS grid type,
writes two files to disk: the first file contains the interior
points, the second the outside boundary.

Grid files have the same record format as the map boundary files
listed in the previous section.

9. Sources of Digital Map Data for use with VERSAMAP

VERSAMAP will generate maps from the following databases, available
commercially, as shareware, or in the public domain. In addition,
the program will accept input in a simple ASCII format. VERSAMAP
recognizes the various databases by their file extensions. The two
most complete databases are Micro World Data Bank II and the World
Digitized, both of which are available from shareware disk vendors.


World Data Bank I
File extension DAT

A database containing 79,000 latitude, longitude points. Data are
stored as 20 character ASCII records on 5, 5.25 inch, 360K disks
which are available from the National Technical Information Service,
United States Department of Commerce, 5285 Port Royal Road,
Springfield, VA 22161.


Micro World Data Bank II
File extensions PNT, ALL, CCI, MAP

A database in the public domain containing 178,068 latitude,
longitude points. Latitude and longitude are rounded to the nearest
minute and stored as six byte binary records. The complete database
is available on 5, 5.25 inch, 360K disks from shareware disk vendors
such as: Big Byte Software, P.O. Box 14008, Arlington, Texas 76094;
Gemini Marketing, Inc., P.O. Box 640, Duvall, Washington 98019; and
The Software Labs, 3767 Overland Ave. #112-115, Los Angeles,
California 90034.

VMAP.MAP and VMAPFAST.MAP, the digital map files on the VERSAMAP
disk, and the map files, MWDB3.ALL and MWDB5.ALL, included with the
registered version of VERSAMAP are part of Micro World Data Bank II
(MWDB-II).

VERSAMAP allows you to plot any of the following geographical
features from MWDB-II: coastlines, islands, lakes, rivers,
countries, states.

VMAP_EXT.DOC version 1.10 Page 20





MWDB-II contains two sets of digital map files. The first set has
the file extension .ALL or .CCI. These files include data for all
geographic features; they differ in the total number of
latitude/longitude points included in each file. The second set of
MWDB-II files has file extension .PNT. Each .PNT file contains
points from only 1 geographic feature.


Micro World Data Bank II Files

Filename Size(bytes) # Points Comment

MWDB1.ALL 1,068,408 178,068 The entire database
MWDB2.ALL 652,428 108,738
MWDB3.ALL 156,960 26,160
MWDB4.ALL 82,080 13,680
MWDB5.ALL 25,890 4,315
MWDB5.CCI 17,988 2,998

COAST.PNT 449,802 74,967 Coastlines
ISLAND.PNT 211,026 35,171 Islands
LAKE.PNT 90,708 15,118 Lakes
RIVER.PNT 169,164 28,194 Rivers
COUNTRY.PNT 134,154 22,359 Country borders
STATE.PNT 13,554 2,259 U.S. state borders


VERSAMAP allows individual files to be plotted in different colors.
Consequently, if you import MWDB-II .PNT files into VERSAMAP, you
can plot geographic features in different colors.

The mapping programs, Expert Maps and Finger Maps, contain a digital
map named WORLD.MAP. This map is a copy of the map file MWDB3.ALL
from MWDB-II, and can be used in VERSAMAP.


The World Digitized
File extensions MPS, MP1

A shareware database containing 100,000 latitude, longitude points
rounded to thousandths of a degree. The database is available on 3,
5.25 inch, 360K disks (in both binary and ASCII format) from
shareware disk vendors.

The World Digitized database is subdivided into directories, one
directory for each continent. This useful feature reduces plotting
time since the user can select only those areas he wishes to map.

Each of the World Digitized directories contains 2 or more map
files. If you wish to plot the entire World Digitized database from
VERSAMAP, you will have to concatenate the individual .MPS(binary)
or .MP1(ASCII) files, since VERSAMAP will not accept more than 9
input files. The VERSAMAP disks contain 2 files, VMAP_FIX.MPS and
VMAP_FIX.MP1, which must be used to concatenate World Digitized

VMAP_EXT.DOC version 1.10 Page 21





files for use with VERSAMAP. These 2 files, VMAP_FIX.MPS and
VMAP_FIX.MP1, force a line break at the end of each World Digitized
file when it is concatenated.

For example, to concatenate the World Digitized binary .MPS files in
the Europe subdirectory for use with VERSAMAP, use the following
form of the DOS copy command:

COPY /B E0.MPS+VMAP_FIX.MPS+E1.MPS+VMAP_FIX.MPS+E2.MPS+
VMAP_FIX.MPS+E3.MPS EUROPE.MPS

where EUROPE.MPS is the concatenated file.

A similar procedure is used to concatenate the World Digitized ASCII
.MP1 files for use with VERSAMAP:

COPY E0.MP1+VMAP_FIX.MP1+E1.MP1+VMAP_FIX.MP1+E2.MP1+
VMAP_FIX.MP1+E3.MP1 EUROPE.MP1

Spurious diagonal lines will be plotted if you do not insert the
VMAP_FIX.MPS or VMAP_FIX.MP1 files between the World Digitized files
when they are concatenated for use with VERSAMAP.


Cartog
File extension BIN

The mapping program CARTOG (Byte Magazine, page 329, December 1987)
includes the database WORLDMED. This database contains 15,000
latitude, longitude points rounded to hundredths of a degree and
stored as 6 byte binary records. The mapping program and the
WORLDMED database are available on disk from Byte Magazine.

The authors of CARTOG also sell a larger map database, WORLDBIG,
which contains 95,000 points. Details and price are on the CARTOG
disk.


Importing Your Own Data into VERSAMAP
File extension PRN

In addition to the above file formats, VERSAMAP will also accept
latitude, longitude values in the following ASCII format. The line
header field is used to indicate the beginning of each new line
segment; -1 indicates the beginning of a new line segment, 0
indicates subsequent points in the line segment. Latitude and
longitude are given as decimal degrees; negative values represent
South latitude or West longitude.







VMAP_EXT.DOC version 1.10 Page 22





Record Format for User Supplied Data


field #1 - line header: -1 for new line segment
0 for point within line segment
field separator: one or more spaces (ASCII 32)
field #2 - latitude: decimal degrees, south latitude is
negative
field separator: one or more spaces (ASCII 32)
field #3 - longitude: decimal degrees, west longitude is
negative
end of record: carriage return (ASCII 13),
line feed (ASCII 10)


Records with this format can be generated by most word processors
and text editors. The file VMAPUSER.PRN on the VERSAMAP disk is a
short file using the above ASCII format. You can use VMAPUSER.PRN
to study the appearance of the different symbol shapes, sizes, and
colors that VERSAMAP can plot.


10. Use of VERSAMAP with Graphing Programs

VERSAMAP can be used to prepare publication quality maps in
conjunction with suitable graphing programs. To be useful in
preparing maps, a graphing program should be able to:

a) handle large data sets;
b) use more than 1 data set per graph;
c) physically separate the x and y axes, so that they do
not show on the figure;
d) connect individual points on the graph with lines; and
e) exclude data which exceeds the X- and Y-axis limits.


To print a map using a graphing program, import the map grid and the
output map boundary files into the program.

If there are two map grid files, the points in the first map grid
file should be plotted as dots, and the points in the second map
grid file should be connected by lines. If there is only one map
grid file, you can connect the grid points by lines or not,
depending on how you want the graticule to appear.

The X- and Y-axes are scaled using the values of X-axis Length and
Y-axis Length listed under Relative Length of Axes on Report Screen
1. The relative X-axis Length is defined as 1.000000 for all maps;
the relative Y-axis Length may be less than or greater than unity,
depending on the projection and graticule chosen.





VMAP_EXT.DOC version 1.10 Page 23





Starting values of the X- and Y-axes should be set at 0. The ending
values of the X- and Y-axes will depend on your graphics program,
but in general they will one or both of the values listed under
Relative Length of Axes on Report Screen 1.

You should configure the graphing program for data clipping (i.e.
exclude points which lie outside the limits of the X- and Y-axes).
This will prevent the dummy points (X = 5.000000), which indicate
new line segments (see Section 8, Map Output Filenames), from being
plotted.

Map and grid output files produced by VERSAMAP have been
successfully imported into the technical graphics programs, Grapher
and SigmaPlot. For use with SigmaPlot, dummy points (X = 5.000000)
which indicate line breaks in map output files must be converted to
dashes (X = --------), indicating missing data, before the files are
imported into SigmaPlot. Changing the dummy points from 5.000000 to
-------- can be done using the replace command in Edlin or the
search and replace command in a word processor.


11. Program Compatibility

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
