Method Details

apply

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
