Hello, all. I am trying to understand if/how MapServer can take advantage
of GDAL's abillity to read GRASS groups per
http://www.gdal.org/frmt_grass.html Is it possible to display RGB
composites as William surmises above? Do the GRASS layers have to be 0-255
integers strictly or will a float work as long as it has 256 levels? How do
the PROCESSING directives play into this? It's not clear to me which, if
any, of the directives are relevant to GRASS layers -- maybe there is
another page somewhere with more details beyond the "Raster Data Access"
page. BTW, I believe MS _does_ now use the GRASS color tables.
Neil,
MapServer can display from floating point raster bands and you can rescale
on the fly using the various processing scaling options. I'm a bit vague on
the state of the gdal-grass driver but experimentation with gdalinfo
reporting should verify the current state of things.
Best regards,
