<p class="MsoNormal">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?<o:p></o:p></p>

<p class="MsoNormal">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.)<o:p></o:p></p>

<div>
<p class="MsoNormal">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. (<a href="http://trac.osgeo.org/mapserver/ticket/1305">http://trac.osgeo.org/mapserver/ticket/1305</a>)
Any insight on whether this is still the plan?<o:p></o:p></p>
