WHAT OUR HAPPY STUDENT SAY
What’s New in GeoAlchemy 2
- GeoAlchemy 2 supports PostGIS’
geometry
type, as well as thegeography
andraster
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.
