Given a particular RasterExtent (geographic area plus resolution) for the entire tiled raster, construct an ResolutionLayout which will manage the appropriate geographic boundaries, and resolution information, for each tile.
Given an extent and resolution (RasterExtent), return the geographic X-coordinates for each tile boundary in this raster data.
This method is identical to getXCoords except that it functions on the Y-axis instead.
Return the total number of columns across all the tiles.
Return the total number of rows across all the tiles.
