GeoAlchemy 0.4

Using SQLAlchemy with Spatial Databases

GIS Support for SQLAlchemy.

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.

Requirements

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.

Supported Spatial Databases
