Hi Chris,
I recommend installing a recent copy of GDAL and trying out the
'gdaldem' tool:
http://www.gdal.org/gdaldem.html
The idea would be to assign a color table to your data before
rendering with Mapnik. Built in support is surely desirable but not
implemented.

Dear Mapnik users,
According to the Mapnik wiki, The RasterSymbolizer is used to render
an image from any GDAL supported format
But the css parameters for the RasterSymbolizer seem to be limited
to opacity, scaling and mode.. as per this page
http://trac.mapnik.org/wiki/RasterSymbolizer
I'm trying to define a colour ramp ideally for one of the GDAL
supported raster formats, but cannot see how to do this.
Is this possible with the current version?
TIA,
Chris
