All Implemented Interfaces:
org.apache.jena.sparql.function.Function
public final class FUN_GeoJSONGeometry extends org.apache.jena.sparql.function.FunctionBase1
Binding function fun:GeoJSONGeometry extracts the Geometry member from a Feature object as a wktLiteral.

See Live example

  • Param 1 is a GeoJSON Feature object in JSON;
  • Result is a GeoSPARQL wktLiteral.

The following geometry types are supported: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection.
