I applied the same method actually (after a bit thinking and reevaluation of my first idea). I prefer to use v.in.ascii -t -r -z input= fs= z= out= , because I'm interpolating the points with v.surf.bspline (bilinear, to be more precise) afterwards.
I have some more questions now. Sorry, but I don't know if I should put them in a different e-mail and subject... I used r.horizon module to build horizon view for 16 directions, consequently I received as a result 8 output raster maps: r.horizon elevin=demb30_5_combined@FlemishArdennes direction=0 horizonstep=45 maxdistance=10 horizon=SVF_demb30_5 After that I combined them witn r.mapcalc but with simple addition only: r.mapcalc: 'SVF_demb30_5_0@FlemishArdennes + SVF_demb30_5_1@FlemishArdennes + SVF_demb30_5_2@FlemishArdennes + SVF_demb30_5_4@FlemishArdennes + SVF_demb30_5_5@FlemishArdennes + SVF_demb30_5_6@FlemishArdennes + SVF_demb30_5_7@FlemishArdennes' Is this approach correct? And how can I change the range value of the output raster after I have set up first color table with r.colors color=grey. I want to change the range from 0.0-1.0 to something else, like 0.7-1.0 for example to get more contrast or brightness. The last is in fact the question from my first e-mail (see up) with this subject. Thanks a lot for the help!
