John The DATARANGE / COLORRANGE keywords will be fully documented by 6.2 but they have been present in MapServer for years (since 4.6 or so).
We used DATARANGE / COLORRANGE for dem display in this years FOSS4G WMS Benchmarking effort.

I'm looking to display a raster digital elevation model in mapserver. My data is in flat files, img and tiff. I'd like to display this data as a continuous gradient color range, rather than using CLASS categories/bins for specific colors. Is it still tru ethat this is not possible, easily? One method (passed to me on this list) was too generate the colored image I want in another program, using GMT or similar tool, then use that in mapserver. This seems like the best option but is non-trivial to someone who hasn't done this before. (though not terribly difficult.) I also read about the use of DATARANGE and COLORRANGE in mapserver. However, these are not in the documentation. Are these available in trunk only? A ticket was generated that seems to say this will be included with MS 6.2. (http://trac.osgeo.org/mapserver/ticket/1305) Any insight on whether this is still the plan? Thanks for your help and advice. - John *********************************************** John Callahan, Research Scientist Delaware Geological Survey, University of Delaware URL: http://www.dgs.udel.edu ************************************************* _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org<mailto:mapserver-users@lists.osgeo.org> http://lists.osgeo.org/mailman/listinfo/mapserver-users
