I wrote to the GRASShopper list a long time ago offering a file that contained
an assortment of mapgen replies which I had collected from the list over
a period of time. I originally offered it to the one person who asked about
MAPGEN at the time.
I got about a hundred requests from other list users for the file...it was
sort of overwhelming...and I never have quite gotten to do a mailing to
multilple people on the list (whose requests are now in yet another
file...).
Joyce has shamed me into putting this file of disorganized mapgen info onto
the list for all to see. If you are not interested in mapgen, hit control-c
now and erase this message. I'm sorry to those of you who are not interested.
NO REPLIES OR THANKS OR ADMONITIONS OR THOUGHTS ARE NECESSARY IN RETURN!

Besides the MAPGEN software that is distributed with GRASS4.0, you
might want to ftp to charon.er.usgs.gov and download the most recent
version of MAPGEN and its related programs. This anonymous ftp site
also contains additional documentation (the USGS Open-File Reports on
MAPGEN) that is not distributed with GRASS. Although there is a far
bit of material to read over, I have found it to be very thorough. The
installation instructions are also relatively straightforward. I don't
use any HP pen plotters but there appears to be drivers for such
devices in the MAPGEN package.
cheers!

The source files for mapgen are in the directory src.related/mapgen
They do NOT get compiled as part of the standard install, but it is a
relatively simple matter to get that done (there is a standard grass4.0
make file to do the job; just type gmake4.0). You do need to identify
the type of plotter you are going to use before you make. The readme
file gives directions of how to do that.
The docs for mapgen are in the directory also, and grass headquarters
has a hardcopy you can buy. The best way to use mapgen is with the SCS
interface, which is provided in the source directory also. You do however
need to compile some stuff in the src.contrib/SCS directory also.
The make file will take care of all that for you if all the sources are in
the "standard place".
Good luck.

Nancy-
Let me see if I can answer all your questions (if I miss something,
please re-ask).
First: the user's reference manual, MAPGEN documentation, and
PPM documentation are all on-line with GRASS 4.0. You can get a copy
for yourself by printing these out. If you want a postscript version
of the reference manual, that is available on our ftp site.
A draft copy of the User's Guide is already on the ftp site as well.
Please be advised that this is really not finished in terms of being
updated to match 4.0 programs. According to the author, we should have
a final version here in about 5 or 6 weeks. When we have that, we
will put it on the ftp site as well.
The fixes to 4.0 (m.dem.extract, tiger updates, etc.) are also on the
ftp site.
The help guide is on-line with GRASS4.0, but we will be putting a separate
electronic copy onto the ftp site sometime within the next 2 weeks, along
with copies of completed 4.0 tutorials (there are one or 2 that are
not completed, but many are ready for distribution).

If you want to use GRASS to make maps to send to a pen
plotter you must use MAPGEN, because p.map creates
rasterized maps that can not be plotted on a pen plotter.
You could move data over into AutoCad, but MAPGEN comes
with GRASS4.0 and can be used to make good maps. Use the
GRASS-MAPGEN Interface written by the Soil Conservation
Service and released with GRASS4.0.
> OK, where is MAPGEN?
The MAPGEN and GRASS-MAPGEN Interface code is distributed with
GRASS4.0 under src.related. Look for the directory
$GISBASE/src.related/mapgen. [$GISBASE represents the directory
where GRASS is loaded on your computer(s).]
> If it isn't already compiled on my system, how do I do that?
I use GRASS and MAPGEN, but I don't know doodoo about compiling
code. See the README file in $GISBASE/src.related/mapgen. Ask
a programmer/system-type person in your office for help.
> When I compile it will it ask me what plotters I want to use
> or is there another step to tell it that?
No, you will not specify plotters at the compiling stage.
There is a file called devlist.c that lists plotter devices
that might be usable with MAPGEN (look for
$GISBASE/src.related/mapgen/SCS/plotter/devlist.c). The
devices listed there are really potential formats of MAPGEN
output ("potential" because some of them work and some of them
do not). For example, the MAPGEN command line
plotter -d hpgle maplayerfile
will send the file called "maplayerfile" to standard output in
the HPGL format for e-size paper (HPGL stands for Hewlett-
Packard Graphic Language, a widely used plotter format).
The way I have my plotter set up, the line from the plotter is
connected to the serial port called ttya on my Sun computer.
To send MAPGEN plots on e-sized paper using HPGL, I use this line:
plotter -d hpgle file1 file2 [etc.] > /dev/ttya &
So if MAPGEN is compiled correctly, you choose your plotter by
using the appropriate format and by sending the output to the
correct "plug".
Since you have a Hewlett-Packard plotter, you should have no problem
just using hpgla, hpglb, hpglc, hpgld, and hpgle as your device choices.
Also, the plotter command (a USGS MAPGEN command) can easily be put
into a shell-script that asks the user for the device wanted. Try
modifying plot.sh in (perhaps) $GISBASE/sun4/mapgen/interface.

Hi:
I am a grass's user from almost one year ago, an I am interesting in MAPGEN.
Where is MAPGEN and How can I get it?
MAPGEN is two things. First, a USGS produced package; second, an interface
between GRASS and this USGS package. Both are available with GRASS 4.0
which is available via anon ftp from moon.cecer.army.mil. The latest version
of the first is available from: charon.gd.usgs.gov

You need to get graphics,proj,mapgen,[xzoom] and build in that order.

re: your question about obtaining GRASS for the CDC 4000
platform....
From a GRASS Information Center document called "Acquiring
GRASS Software", 06 November 1991:
USACERL does not distribute GRASS for the CDC 4000. But
it is available from a company in Montreal:
Logiciels et Applications Scientifiques, Inc.
1570, rue Chabanel Quest
Montreal, Quebec, H4N 1H4, Canada
POC: Gilles Clement 514-858-1104
FAX 514-398-9373
Things might have changed since November regarding GRASS
on CDC's. While I am checking, go ahead and give the
folks in Canada a call...
Call Jerry Thompson, Paul Loechl, or me at USACERL if you
have any more questions.

Subject: Device drivers for Mapgen
Status: RO
To any MAPGEN-user:
I have a question about device-drivers for MAPGEN. We have a Roland DXY-880
plotter at our institute, which accepts HPGL-instructions. The drivers
I have available for MAPGEN (hpgl, 7475) convert MAPGEN-data to HPGL-
format, but the plot's boundaries fall outside the plotter's. The reason
for this is simple: according to the Roland-manuals, B(A3)-sized paper has
X,Y-limits of 15200,10800; the 7475-driver assumes X,Y-limits of 16640,10365
for B-sized paper. I tried to change this in the Dhp7475.c file in the
./graphics/plotter directory, but the changes are not implemented. Maybe
this is because the ./lib/libdev.a file needs to be changed. Is there
anyone who can tell me how to overcome this problem? I now use a workaround
by scaling the plot using `plotter -s`, but I can't get any map out of it
that has the correct scaling, which is a bit annoying.
I hope someone can help me with this.

Philip and those concerned;;
Your problem with the HPGL driver in MAPGEN is a common one since
different plotter layouts allow for different plotting areas on a
standard size paper. The solutions!!!.
First you attempt to chage the driver is correct. If you are using
The GRASS MAPGEN code in src.related you must:
1) change Dhp7475.c
2) set these environment variables
GISBASE="PATH to GRASS executables"
GRAPHB=$GISBASE/mapgen/bin/plotter:$GISBASE/mapgen/gfonts/:sr:
BIN=$GRAPH/bin
RANLIB=ranlib "or echo if your system doesn't have ranlib"
INCL="PATH to GRASS src"/src.related/mapgen/include
MLIB="PATH to GRASS src"/src.related/mapgen/lib/LIB.sun4
2) In the Dhp7475.c directory run "make libdev"
3) cd to src.related/mapgen/SCS/plotter and run the
GRASS gmake facility.
If you do not want to bother fixing the code it may be possible to
allow an additional margin on you maps to compenstate for the loss of
plotting area.
Also if you are running a recent version of the MAPGEN software and your
plotter is connected directly to your host machine you can have MAPGEN talk
read the plotting size fron the plotter using the following command.
plotter [options] [overlay files] < "tty device name" > "tty device name"
If you have any further problems let me know.

Subject: MAPGEN
If you are trying to compile MAPGEN with the SCS interface you
should review the README file in src.realted/mapgen. I have to
appologize due to last minute name changes the README file refers
to "src.contrib/SCS/misc/g.setproj" this should be
"src.contrib/SCS/misc/m.setproj".
The GRASS/MAPGEN interface requires that at a minimum the map projection
support in SCS contributed code also be installed. This code
is in:
src.contrib/SCS/misc/FIPS_proj
src.contrib/SCS/misc/g.setproj
Atleast this is the structure that exists on our systems at SCS.
I have never used or installed anything called g.project.

Subject: Another MAPGEN question
I was wondering if anyone knows what the Rev # is of the mapgen code that
currently resides on moon. I grabbed the mapgen code off of charon.er.usgs.gov
recently, and the versions are as follows:
graphics-4.6
mapgen-4.2
proj-3.1.2
xzoom-2.01
The mapgen-man at USGS said that there may be some conflicts with the SCS
interface and the new versions of mapgen. What's the update status on this,
or is it as it seems to be, sorta ad-hoc, it works great the first time, don't
know who keeps up on this thing, go with the flow sorta code/interface ?
Any help is appreciated,

Subject: MAPGEN make
Prior to compiling MAPGEN from unsupported/related on moon, the reference to
'g.setproj' in Gmakefile should be changed to 'm.setproj'.
