Class RasterAsPointCollectionProcess

Object

RasterAsPointCollectionProcess

All Implemented Interfaces:

RasterProcess

public class RasterAsPointCollectionProcess
extends Object
implements RasterProcess

A process that wraps a GridCoverage2D as a collection of point feature. Optional parameters can be set:

• targetCRS : can be used for calculating the GridConvergence Angle of each point
• scale : can be used for scaling the input coverage
• interpolation : can be used for setting the interpolation method when Scaling is applied
• emisphere : forces to indicate the hemisphere for each point

clipOnRenderingArea

public boolean clipOnRenderingArea()

This process does not need, nor can use, extra pixels in input outside the rendering area, when used as a rendering transformation. If those are present, tiling will result in mis-aligned points when scaling down (in addition, a user should try to use a scale down factor that always results in an integer number of pixels, to ensure proper cross-tile alignement).
