Class AreaGridProcess2

java.lang.Object
  org.geotools.process.raster.gs.AreaGridProcess2

All Implemented Interfaces:

org.geotools.process.gs.GSProcess

public class AreaGridProcess2
extends Object
implements org.geotools.process.gs.GSProcess

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
