Collection of methods to fetch spatial metadata in SFS database like PostGIS or H2Spatial. Theses functions can be commonly used either in PostGIS or in H2. Spatial utilities publish also a DataSourceFactory wrapper that provide JDBC Wrapper for spatial functionality.

There is a newer version: 1.2.4
