Well, I think it wasn't that hard anyway. Here is how I did it. First, you
should calculate the angle of each point with respect to the center of the
circle (the observer's position). Then you can select those points which
reside in the wanted range.

Hi all,
I downloaded some Landsat data from the USGS. When I opened the GeoTiff in
GRASS using r.in.gdal, I got the Blue, Green and Red bands. How do I get the
near infrared, two medium infrared, thermal, and panchromatic bands.
I am using GRASS 6.4 RC6 on OS X.

The FOSSGIS-conference is the largest german-language conference for
Free and Open Source Software for GIS and Free Geodata. Today, the
Conference Committee announced the "Call for location" for 2011. Because
the conference-language is german, the CfL is either:

Hi,
I have used the r.los function to calculate the viewshed from a point in the
map. The result is a subset of a circle around that point. Now, I want to
select a sector of this circle which has an angle of 45 (or whatever), and
nullify the rest of the circle. Any idea on what is the best way to
Hi List,
I understand it may sound kind of strange problem.
I need to know how GRASS manages complex numbers in a map.
I.e. i produced a map with r.mapcalc using a formula and in some cell I
could have complex.
In GRASS i have not. I tried the same formula in MATLAB and I have, but
MATLAB manages

Hello,
I'm a brand new GRASS user and I only need it for a very specific task: I'm
using an ASCII raster map (created in Arc) of the world for spatial simulations
in population genetics.
Currently, the land is represented by 1s and water by 0s. I want to specify
arbitrary regions that will be r

Dear all,
I wonder how many GRASS related talks have been submitted. Myself, I have
sent one to the academic track and ask myself if to submit also a general
talk like "25 years of GRASS" (anyone else already?) and perhaps also
