#498: r.sun2 commissioning trials --------------------+------------------------------------------------------- Reporter: hamish | Owner: hamish Type: defect | Status: assigned Priority: major | Milestone: 6.4.2 Component: Raster | Version: svn-develbranch6 Keywords: r.sun | Platform: All Cpu: All | --------------------+-------------------------------------------------------
Comment(by dylan): Here is the code used to produce the example images. Note that the beam and diffuse radiance maps created by r.sun are clearly incorrect when slope and aspect maps are not specified. The output looks correct when slope and aspect are specified. The beam and diffuse radiance maps are attached as: "beam_rad.015.jpg" / "diff_rad.015.jpg" (only elevation given), and "sa_beam_rad.015.jpg" / "sa_diff_rad.015.jpg" (slope and aspect given). The DEM used can be found here: http://basho.dyndns.org/~dylan/temp/elev30.tif {{{ g.region rast=elev30 res=30 -pa r.slope.aspect elevation=elev30 slope=slope30 aspect=aspect30 r.sun -s --o elevin=elev30 day=15 beam_rad=beam_rad.015 diff_rad=diff_rad.015 refl_rad=refl_rad.015 glob_rad=glob_rad.015 r.sun -s --o elevin=elev30 slopein=slope30 aspin=aspect30 day=15 beam_rad=sa_beam_rad.015 diff_rad=sa_diff_rad.015 glob_rad=sa_glob_rad.015 refl_rad=sa_refl_rad.015 }}} -- Ticket URL: <https://trac.osgeo.org/grass/ticket/498#comment:19> GRASS GIS <http://grass.osgeo.org>
