GIS Support for SQLAlchemy.
GeoAlchemy is an extension of SQLAlchemy. It provides support for Geospatial data types at the ORM layer using SQLAlchemy. It aims to support spatial operations and relations specified by the Open Geospatial Consortium (OGC). The project started under Google Summer of Code Program under the mentorship of Mark Ramm-Christensen.
Requires SQLAlchemy > 0.6. Supported on Python 2.5 and Python 2.6. Should also work with Python 2.4 but has not been tested. It also requires a supported spatial database.
At present PostGIS, Spatialite, MySQL, Oracle and MS SQL Server 2008 are supported.
GeoAlchemy is at an early stage of development. Its mailing list is available on Google Groups. The source code can be found on GitHub. Also, feel free to email the author directly to send bugreports, feature requests, patches, etc.
