Class SpatialRequestHelper

Object

SpatialRequestHelper

public class SpatialRequestHelper
extends Object

Helper class which takes coverage's spatial information input (CRS, bbox, resolution,...) and a set of request's parameters (requestedCRS, requestedBBox, requested resolution, ...) and takes care of computing all auxiliary spatial variables for future computations.
