[postgis-users] Could not add all rasters to a table

[Bborie Park]

Ah.  I see that the Windows installation doesn't come with the gdal
utilities.  You can install GDAL using the OSGeo4W installer.

http://trac.osgeo.org/osgeo4w/

Once GDAL is installed, you should be able to call gdalinfo on the
raster files and get a dump of the raster metadata.

Overlap isn't a problem.  The problem is that one of the rasters is not
on the same "grid" as the other rasters.

Check the values for the upper-left corner, scale and skew.  The scale and skew should be the same while the upper-left corners should be divisible without a remainder...
