    • createBboxes

      public org.locationtech.jts.geom.Geometry createBboxes(String[] bboxes)
      Creates a unified Geometry object out of the content of the given String array.
      Parameters:
      bboxes - String array containing the lon/lat coordinates of the bounding boxes. Each bounding box must consist of 2 lon/lat coordinate pairs (bottom-left and top-right).
      Returns:
      Geometry object representing the unified bounding boxes.
      Throws:
      BadRequestException - if bboxes coordinates are invalid

    • createCircularPolygons

      public org.locationtech.jts.geom.Geometry createCircularPolygons(String[] bpoints)
      Creates a Geometry object around the coordinates of the given String array.
      Parameters:
      bpoints - String array containing the lon/lat coordinates of the point at [0] and [1] and the size of the buffer at [2].
      Returns:
      Geometry object representing (a) circular polygon(s) around the given bounding point(s).
      Throws:
      BadRequestException - if bcircle coordinates or radius are invalid

    • createBpolys

      public org.locationtech.jts.geom.Geometry createBpolys(String[] bpolys)
      Creates a Polygon out of the coordinates in the given array. If more polygons are given, a union of the polygons is applied and a MultiPolygon is created.
      Parameters:
      bpolys - String array containing the lon/lat coordinates of the bounding polygon(s).
      Returns:
      Geometry object representing a Polygon object, if only one polygon was given or a MultiPolygon object, if more than one were given.
      Throws:
      BadRequestException - if bpolys coordinates are invalid

    • createGeometryFromMetadataGeoJson

      public void createGeometryFromMetadataGeoJson(String geoJson)
      Creates a Geometry object from the given GeoJSON String, which is derived from the metadata.
      Throws:
      RuntimeException - if the derived GeoJSON cannot be converted to a Geometry

    • createGeometryFromGeoJson

      public org.locationtech.jts.geom.Geometry createGeometryFromGeoJson(String geoJson, InputProcessor inputProcessor)
      Creates a Geometry object from the given GeoJSON String. It must be of type 'FeatureCollection' and its features must be of type 'Polygon' or 'Multipolygon'.
      Throws:
      BadRequestException - if the given GeoJSON String cannot be converted to a Geometry, it is not of the type 'FeatureCollection', or if the provided custom id(s) cannot be parsed
