PostGIS for PostGres |
For many years there has been a limited choice of geodatabases when looking for a single solution for all geodata models. Only
Oracle Spatial and
ESRI offered comprehensive coverage of spatial models.
Oracle Spatial provided database models and algs for vector, network, raster and topology in addition to the usual database refinements and in database geocoding.
ESRI offered ArcGIS Server with comprehensive support for Vector, Network and Raster models but left topology to the clients and had no offering for geocoding.Competitors such as PostGIS, MapInfo Spatialware, Microsoft SQL Server and MySQL only offered support for vectors.
It seems the status quo may be about to change....
