We're trying to add grass raster layers to a mapserver (UNM) application, but
we encounter problems. Our .map definition is:
but the raster (a Landsat map) is not displayed correctly. I assume this is
related to the mentioned 8/24 bit limitation mentioned in
However, I find contradictory notes about this:
- in the web page I find " GRASS raster map directly read from location must
be in 8bit", whereas in http://grass.itc.it/spearfish/README there is "Hint:
Mapserver currently only displays 8bit/24bit Integer images."
Is there a way to display directly grass rasters in full color, or are we
limited to 8bit (in this case, tiff may be a better choice, but we would
prefer to avoid data duplication).
And where exactly is the limitation? If it is in gdal, how can qgis display
the same rasters correctly?
All the best.
