      Method to clock wise rotate a geometry of a defined angle
      Parameters:
      geometry - the geometry to be rotated
      angle - in degree

    • rotateGeometry

      public static void rotateGeometry(org.locationtech.jts.geom.Geometry geometry, int angle)
      Method to counterclock wise rotate a geometry of a defined angle
      Parameters:
      geometry - the geometry to be rotated
      angle - in degree

    • centerGeometry

      public static void centerGeometry(org.locationtech.jts.geom.Geometry geometry, org.locationtech.jts.geom.Coordinate displacement)
      Move a geometry to a defined coordinate
      Parameters:
      geometry - the geometry to be moved
      displacement - the new geometry coordinate

    • createEmptyGeometry

      public static org.locationtech.jts.geom.Geometry createEmptyGeometry(Class geometryClass, org.locationtech.jts.geom.GeometryFactory geometryFactory)
      creates an empty geometry matching the geom type set already or an empty geom collection if that fails
      Parameters:
      geometryClass - the geometry Class
      geometryFactory - the GeometryFactory to create the empty Geometry
      Returns:
      an empty Geometry of the specified class
