Class CoverageReadRequest

Object

CoverageRequest

CoverageReadRequest

public class CoverageReadRequest
extends CoverageRequest

Request information from a CoverageSource.

Note that we are working with the assumption that the queried coverage has separable dimensions.

Field Details

rasterArea

protected Rectangle rasterArea

The requested area in the destination raster space.

This field shall basically contain the screen dimension of the requested area in pixels.

UML property:

name="rasterArea"

geographicArea

protected ReferencedEnvelope geographicArea

The requested area in geographic coordinates, which means the area in destination world space which we want to get data for.

UML property:

name="geographicArea"

gridToWorldTransform

protected MathTransform2D gridToWorldTransform

The request MathTransform2D which would map the pixel into the requested world area.

Note that having a raster are and a world area is not enough, unless we have a simple scale-and-translate grid-to-workd transform.

UML property:

name="gridToWorldTransform"
