Hi, this is my first post and I hope someone could help me. I'm using r.sun for computing a solarmap of the alpine arch in Friuli Venezia Giulia (IT). I'm using this command:
r.sun -s elevin=dem_40_fvg_wgs84 aspin=asp_fvg_wgs84 slopein=slo_fvg_wgs84 lin=1.5 alb=0.2 horizonstep=10 beam_rad=irr_fvg1 insol_time=ins_fvg1 diff_rad=diffuse_irr__fvg1 refl_rad=ground_refl_fvg1 glob_rad=total_irr_fvg1 day=1 step=0.25 dist=1.0 numpartitions=1 --overwrite But the resultant map have a lot of artifacts (lines of pixels with wrong values, see the attachment) http://osgeo-org.1803224.n2.nabble.com/file/n6917645/r.sun.jpg I've tried to delete "aspin" and "slopein" parameters and i've changed "step" and "dist" with no results. What can i do for remove this artifacts? Except for this problem the map is good. I'm using Grass6.4.1. My OS is W7 64bit. thx Sergio p.s. sorry for my english -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/r-sun-artifacts-tp6917645p6917645.html Sent from the Grass - Dev mailing list archive at Nabble.com. _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
