WHAT OUR HAPPY STUDENT SAY

What’s New in GeoAlchemy 2

• GeoAlchemy 2 supports PostGIS’ geometry type, as well as the geography and raster types.
• The first series had its own namespace for spatial functions. With GeoAlchemy 2, spatial functions are called like any other SQLAlchemy function, using func, which is SQLAlchemy’s standard way of calling SQL functions.
• GeoAlchemy 2 works with SQLAlchemy’s ORM, as well as with SQLAlchemy’s SQL Expression Language (a.k.a the SQLAlchemy Core). (This is thanks to SQLAlchemy’s new type-level comparator system.)
• GeoAlchemy 2 supports reflection of geometry and geography columns.
• GeoAlchemy 2 adds to_shape, from_shape functions for a better integration with Shapely.
