[MS4W-Users] Is MapServer suppose to be able to serve hdf5 images?

[andrew nguyen]

  Hi,

It looks like I misunderstood our requirements. Instead of outputting hdf5
files, we're trying to use Mapserver to serve a standard WMS png tile
output from reading 2D raster data from hdf5 files. We're looking for help
on 2 fronts:


   1.

   Understanding how to format the .map file to READ from the hdf and
   OUTPUT standard WMS png tiles
   2.

   Understanding what geo-reference metadata we need to add to the hdf so
   Mapserver->GDAL will be able to properly read the raster and geo-ref data
