      public List<org.locationtech.jts.geom.Geometry> apply(org.locationtech.jts.geom.Geometry geometry, double gridDistance)

      Cut the geometry up into a grid with mesh size of gridDistance. The grid is centred on the geometry being cut which should reduce the number of pieces it is cut into.

      Parameters:
      geometry - the geometry to cut up
      gridDistance - the grid size
      Returns:
      list of new geometries that have been cut to the grid

    • apply

      public List<org.locationtech.jts.geom.Geometry> apply(org.locationtech.jts.geom.Geometry geometry, double gridDistance, org.locationtech.jts.geom.Point origin)

      Cut the geometry up into a grid with mesh size of gridDistance.

      The grid is formed from the origin. The advantage of this is that many geometries can be cut to the same grid.

      Parameters:
      geometry - the geometry to cut up
      gridDistance - the grid size
      origin - the point to align the segmenting relative to
      Returns:
      list of new geometries that have been cut to the grid
