I'm new to PostGIS (reasonably) - but I'm plagued with one on-going problem: I'm able to access PostGIS from various GIS systems using the main 'postgres' user.Using a newly created user 'gis_viewer' - I've granted SELECT and USAGE on SCHEMA etc.Perhaps the only thing I have not done yet is try...

In this session we create test integer and floating point rasters and query using the Con, SetNull,IsNull geoprocessing tools. We also use a cursor to access the raster attribute table and convert high elevation pixels to points. We also query for the total area above a threshold elevation. أكثر...
