GeoAlchemy: Using SQLAlchemy with Spatial Databases


GeoAlchemy provides extensions to SQLAlchemy to work with spatial databases.

The current supported spatial database systems are PostGIS, Spatialite, MySQL, Oracle, and MS SQL Server 2008.


To install GeoAlchemy use EasyInstall as follows:

$ easy_install GeoAlchemy

Or, download the package, change into the geoalchemy dir and type:

$ python install

GeoAlchemy is known to work with Python 2.5 and Python 2.6, but it should also work with Python 2.4 and 2.7.
