Updating geometry as Multipolygon from Polygon table using PostGIS?
Hiking & ActivitiesHow does PostGIS store geometry data? PostGIS uses a table named geometry_columns to store metadata associated with the geometry columns in the database. The installation of PostGIS automatically creates this table. What is the difference between geometry and Geom in PostGIS? Geometry, where it assumes all of your data lives on a Cartesian plane (like
How to resolve ERROR 010271: Raster does not have an attribute table?
