[mapguide-users] Re: Problem with raster

[Jackie Ng]

That's just a normal warning you get when the GDAL provider could not
determine the extents of the raster image, so the provider just returns an
arbitrarly large extent (+/- 1000000 ). It's a warning because the extent is
usually way too large and a layer that is created off of it usually cannot
be previewed.

I have made a patch for the GDAL provider recently that should drastically
improve the extent detection in this provider. It should return the same
numbers for any raster, as the ones returned by the gdalinfo.exe utility.

Patched versions of the GDAL provider are available here:
http://trac.osgeo.org/mapguide/wiki/MGOS22GdalProvider

It is strongly advised to install this patched provider in the above link.
