Introduction¶
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.
