[postgis-users] bring PostGIS into the raster world

[Mark Fenbers]

QGIS let's me display vector data stored in PostgreSQL.  I can also add 
raster data, such as radar reflectivities and satellite images, from GIF 
or netCDF files.  I'd rather have all this stuff in PostgreSQL rather 
than having to access gridded data from files and vector data from the 
DB.  I believe it's the GDAL library that gives QGIS the generous 
support of raster files.  Perhaps if PostGIS used GDAL, then the list of 
TODOs for this effort would be cut much shorter... (?)
