RE: [GRASS-user] Surface spot interpolates heights for pointis in a feature class from surface

You should take a look at v.what.rast. According to the manual: v.what.rast reads raster value for each point in the vector and updates col column in vector attribute table by this value. The column should be type number (integer, float, double, ... ). If more points have the sa

Etienne, if the main difficulty is about how to combine two criteria in one "r.mapcalc" command, then, I recommend to go through the r.mapcalc manual [1]. There are many examples. Also read the old (but very good) tutorial [2] (which is referenced in the manual). Nikos --- [1]

[GRASS-user] wx python: multiple selection

Hi. Sorry for naive question, but in fact I try to use wx since few days, so maybe I lost something... How to made multiple map selection in wx without repetition of choosing map from list (look for something like control+click in tcltk menu gui) when multiple scope of map is needed (for exa

[GRASS-user] Minimum number of pixels required by i.gensigset (i.smap)

I am trying to find an answer to the question of how many "pixels/per training object" are at least required for i.gensigset (and successively i.smap) to work. I could not find the answer in the (Bouman and Shapiro, 1994) paper. Among my notes I have "if the number of pixels (of a training objec

[GRASS-user] Python script for Reclass from values
