Constructor Detail

GeospatialStatistics

public GeospatialStatistics(BoundingBox boundingBox,
                            GeospatialTypes geospatialTypes)

Constructs a GeospatialStatistics object with the specified CRS, bounding box, and geospatial types.

Parameters:

boundingBox - the bounding box for the geospatial data, or null if not applicable, note that - The bounding box (bbox) is omitted only if there are no X or Y values. - The Z and/or M statistics are omitted only if there are no Z and/or M values, respectively.

geospatialTypes - the geospatial types

GeospatialStatistics

public GeospatialStatistics()
