Markus,

Thanks for you interest to our work.
My name is Timur Kusherbaev,

I work for SJ Geophysics Ltd. (you communicate with Syd Visser several 
days ago).
We use GRASS for geophysical data and I make needed programming to fit 
it to our processing routine.

I send you file SJGeo.tar.gz with 4 programms:

1.  r.recolor - this new program allows to make color management for 
raster map using categories distribution in equal area mode  and 
generate desiring color levels using extended possibilities  for linear 
color interpolation or file color sets. The program works with FP maps  
and has description (file DESCRIPTION in folder with program). This 
program is very usefull to us because able to show maps with different 
kinds of histograms. We hope it will be usefull to others.

2.  s.out.ik - s.out.ik - Converts a GRASS site list file into an ASCII 
file with coordinates and information for icons creation. This file can 
be used directly by program v.in.poly for poligons (vector icons). 
 Program also has description.  This program makes actions which can 
seem similar to another programs but it use range of data to produce 
icons and has some ways to regulate kind of icons.

3.  d.site.labels - I made some changes (xoffset,yoffset,angle of labels 
rotation) - all changes are in     file CHANGES in directory.

4.  r3.to.sites - I also add some possibilities to this program(to 
output in certain range of values) and all  changes also in file CHANGES 
in directory of program.

Also some changes  made with  "r.digit" program which does not work 
properly. But this changes not go to the way which was planed by 
developpers: we only need to get ASCII file with digitized data. I cut 
part of program which try to produce raster map and simly directed 
output to ASCII file. That is enough to our purpuses but I am not shure 
that it will be resonable to others.

We use "ps.map" to prepare scripts and I had to do some work around it. 
It does not make boundary box (probably it is old) and when we try to 
use it in Ghostscript we get message on this subject. So I added it and 
removed from ps.map possibility to make automatic frame around output 
because on the one side it is not usefull when we combine two or more 
files to one script, and on the other side it is possible to add any 
desiered frame from the mapping instructions. Also I included 
possibility to rotate text. But I am not shure about all changes at 
present because the program has a lot of modules and another parts which 
can depend on changed ones. I did not study "ps.map" properly to be 
shure that all changes are correct.
