#256: r.colors enhancement -----------------------------------+---------------------------------------- Reporter: wegmann | Owner: [email protected] Type: enhancement | Status: new Priority: trivial | Milestone: 6.4.0 Component: default | Version: 6.3.0 Keywords: r.colors colors range | Platform: Linux Cpu: Unspecified | -----------------------------------+---------------------------------------- I had the problem that I wanted to display 5 related raster which have different range of values (e.g. raster1: 0-10; raster2: 5-15; raster3: 6-17 etc.) with the same legend (bgyr) so that raster1 is mainly colored in blue, while raster3 has more green/yellow colors and so on.
I managed it with a script and it is also possible by defining the color rules by hand but adding a flag and add all related raster to a r.colors command would be very handy: r.colors map=raster1 raster=raster1,raster2,raster3 col=bgyr -newflag -newflag would scale the colors of raster1 to the range of colors provided by the values of all rasters. Perhaps it is also possible to add 'g.mlist ...' like in r.series for this feature. Martin -- Ticket URL: <http://trac.osgeo.org/grass/ticket/256> GRASS GIS <http://grass.osgeo.org>
