Class GridWrapper

java.lang.Object

org.openjump.core.rasterimage.sextante.rasterWrappers.GridWrapper

Direct Known Subclasses:

GridWrapperInterpolated, GridWrapperNotInterpolated

public abstract class GridWrapper
extends Object

Abstract class for grip wrappers. Grid wrappers are used to get an easy way of accessing raster layers so different layers (i.e. with different extents and cellsizes) can be combined and analyzed together seamlessly, without having to worry about resampling or adjusting them.
