I am wondering if anyone is aware of any individuals or organizations that are using GRASS for radio propagation studies and predictions. I am VERY new to the program, and I am not really aware of its limitations, etc., but it seems that it could be an excellent tool for predicting radio propagation for cellular systems, etc.
If anyone is aware of such uses, or add-on modules, I would like to hear about it. Also, if there are fundamental limitations of the software that would preclude such applications, I would also like to hear about that.
TIA,
Ed

This came up before several months ago (maybe search the archives).
Closest module I can think of is r.los (line of site), but it really
can't account for the bending and drop-off of various EM radiation (like
microwaves). Also, r.los doesn't work well with lat/lon rasters, so
some segmentation might be required depending on the area of interest.
Even so, r.los could probably be used for coarse estimations.
