Raster Data Access documentation

Denis -

No, it cannot - it needs to be stored in a shapefile.  The shapefile
holds both the list of the raster file names and the geographic bounding
box for each raster file.  That's the "index" part - the shapefile
allows MapServer to use it as an index to quickly determine which raster
images in the layer may be needed for the current map-drawing request.
Raster files that couldn't possibly be needed are ignored.

Hi,

Does somebody know why the Raster Data Access documentation says in
the third sentence

http://mapserver.gis.umn.edu/docs/howto/raster_data/#rasters-and-tile-in
dexing
The list of files forming a layer can be stored in a shapefile

Can the file be store to something else than a shapefile?

Thanks,
Denis Nadeau
