Re: [GRASS-user] Adjust opacity in command line
Andy wrote: I have been trying to find a way to adjust the opacity (or transparency, to throw another key word in there) of raster and vector layers using the command line. for two rasters you can use the d.shadedmap module for a similar effect. It's just a wrapper around a trick with the d.his module. examples: http://grass.osgeo.org/grass63/screenshots/images/fourmaps.jpg http://grass.osgeo.org/grass63/screenshots/images/spearfish_catchements.png (see raster screenshots on the homepage for scripts that made those) It's a bit limited in what it can be used for, but for the case of a categorical area map (maybe 'v.to.rast type=area') over a shaded relief DEM it works quite nicely.

[GRASS-user] r.fuzzy.system output definition
Hi GRASS users!
Maybe anyone has already tried the new GRASS GIS fuzzy inference
system (r.fuzzy.system).
I try to do my first fuzzy computation and follow the paper
Jasiewicz, J. 2011: A new GRASS GIS fuzzy inference system for massive
data analysis, Computers Geosciences, 37: 9, 1525-1531.
Unfortunately I get an error saying it can't find the output raster
map which is indicated in the .map file:
r.fuzzy.system maps=path/to/my/test_set.map rules=path/to/my/test.rul
family=Zadeh defuz=bisector imp=minimum res=100 output=output
ERROR: Raster map output not found
my test_set.map file contains beside the other sets also
%output
$ none {both; 0,20,20,40; linear; 0;1}
$ low {both; 20,40,40,60; linear; 0;1}
$ medium {both; 40,60,60,80; linear; 0;1}
$ high {both; 60,80,80,100; linear; 0;1}
The problem is related to the %output in the .map file not the setting
for output=output because there is also an error for following case:
r.fuzzy.system maps=path/to/my/test_set.map rules=path/to/my/test.rul
family=Zadeh defuz=bisector imp=minimum res=100 output=output_
map
ERROR: Raster map output not found
I am using the GUI interface for the module in GRASS GIS 6.5 on Ubuntu
12.04. Any suggestions what I am doing wrong?
Thank you
best regards,
Johannes

[GRASS-user] Script in Grass - Mapcalc and MODIS
Hi, I'm quit new using GRASS and I'm discovering the great possibilities of the program. I'm currently working with rainfall data and I what to add the daily data of a year using r.mapcalc. I'm sure there a quick solution making a script but I'm really beginner in script. Does someone can give me some tutorial or indication? What would be the easier? Bash or python? Does also someone has some experience with MODIS images in hdf format? Is it possible to work with it with GRASS?
