Hello PostGIS users,
I have just installed William Kyng's PostgeSQ/PostGIS packages for Mac
OS X.5
I have been playing with pgAdmin and QGIS with importing shapefiles
into PostGIS. Works dandy.
Now I am wondering how to solve Attribute Calculations.
Years of using ArcGIS and GRASS it is pretty straightforward on those
apps, and am stumped with PostGIS Attribute calculations..
For example, using a polygon feature;
Creating a new column, say AREA and filling with a calculation that is
Hectares.
Thanks!
