How can I add a PostGIS raster layer to my MapServer map?
First you need GDAL 1.7 or higher compiled with PostGIS raster support. GDAL 1.8 or above is preferred since many issues have been fixed in 1.8 and more PostGIS raster issues fixed in trunk version. You can much like you can with any other raster. Refer to MapServer Raster processing options for list of various processing functions you can use with MapServer raster layers. What makes PostGIS raster data particularly interesting, is that since each tile can have various standard database columns, you can segment it in your data source Below is an example of how you would define a PostGIS raster layer in MapServer.
