Class AreaGridProcess

Object

AreaGridProcess

All Implemented Interfaces:

GSProcess, RasterProcess

public class AreaGridProcess
extends Object
implements RasterProcess

A process that build a regular cell grid where each pixel represents its effective area in the envelope in square meters.

Internally the process uses a reprojection to EckertIV to ensure proper area computation. Current limitations:

• won't work for very large rasters since it allocates the entire grid in memory
• area accuracy increases as the cell size shrinks, avoid having cells that occupy sizeable chunks of the world
