Package org.aksw.jena_sparql_api.sparql.ext.geosparql

Class GeoConstraintFactoryWgs

java.lang.Object
org.aksw.jena_sparql_api.sparql.ext.geosparql.GeoConstraintFactoryWgs
All Implemented Interfaces:
GeoConstraintFactory
public class GeoConstraintFactoryWgs extends Object implements GeoConstraintFactory
A bridge between a SPARQL relation that can be constrained to a bounding box and converting matching rows to WKT strings. (Could be extended to also expose JTS geometries and Jena's GeometryWrappers)
