<div>Thanks again for the idea of using multiple classes but I can't seem to get it to work. Has anyone else had success with this method? It seems as though it's applying only the first defined COLORRANGE to full range of the values in the dataset. </div>
<div><br></div><div>I've tried using the below syntax (only COLORRANGE and DATARANGE in each CLASS) as well as the (proposed?) block syntax as defined at <a href="http://mapserver.org/development/rfc/ms-rfc-6.html">http://mapserver.org/development/rfc/ms-rfc-6.html</a> (which gives me errors for RANGEITEM and invalid hex color for MINCOLOR.) </div>

Thanks for all your responses. I have COLORRANGE / DATARANGE working fine in my map file. Works very well. I'm also looking at using gdaldem for a more custom color scale. Thanks again.

<div>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). </div>

I know this has been asked before but I thought I'd ask to see if anything changed.
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>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.)</div>
<div><br>
</div>
<div>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" target="_blank">http://trac.osgeo.org/mapserver/ticket/1305</a>)
Any insight on whether this is still the plan?</div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks for your help and advice.<br>
