Justin,
What does "NG" stand for in PostgisNGDataStoreFactory? I tried the following
code
...prepare postgis connections params...
jdbcDataStore = pgNgDataStoreFactory.createDataStore(params);
SimpleFeatureType simpleFeatureType = jdbcDataStore.getSchema(typeNames[0]);
System.out.println("crs code: " +
simpleFeatureType.getCoordinateReferenceSystem().getName().getCode());
...
I am getting null on getCoordinateReferenceSystem(), but the table in my
PostGIS database has srid as 4326 if I execute something like:
SELECT ST_AsEWKT(the_geom) FROM table WHERE gid=1
Do you know why crs is null for a simple feature type?
Thanks.
