ObjectGrassCoverageReadParam
public class GrassCoverageReadParam
Represents the read parameters in the geotools space, as opposed to GrassBinaryImageReadParam that are for the imageio space.
Represents the parameters needed by the GrassCoverageReader for reading coverage, i.e. the portion and resolution of the map you want to get from the GridCoverageReader.
The needed parameters to read a GRASS raster map, are the following:
All these values are already handled in the JGrassRegion, so that has to be supplied in order to choose a region different from the native data region.
Note: it is enough to have bounds and row-cols, or bounds and resolutions, or also a corner and row-cols and resolutions.
