Hmm. I was hoping I could add geospatial support to SQLAlchemy itself rather than for a specific web framework. I think GeoDjango wraps the geospatial C++ libraries (GDAL, GEOS, PROJ) with PostGIS but otherwise most of the core functionality seems to be in the geospatial C++ libraries. I have also been tinkering with Alessandro Furieri's Spatialite for SQLite3 and I think it would be a real boon if one could add geospatial support to SQLAlchemy via Spatialite as well as PostGIS. You are saying that we can save work by writing it as a plugin to GeoDjango, but I really like Pylons. Certainly, I can start with the postgis.py example and use the GeoDjango API and MapFish API as references. The MapFish community seems to have integrated PostGIS with Pylons already and maybe I can ask them how they feel about a geospatial extension for SQLAlchemy? We have a need for this at the lab because most of our custom desktop GIS applications use SQLite and SQLAlchemy seems like a great way to glue them all together. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
