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><br clear="all"><div>- John</div>

<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>

<div>We used DATARANGE / COLORRANGE for dem display in this years FOSS4G WMS Benchmarking effort.</div>

</div></div><div><div></div><div class="h5">
<div><br>
</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>
