Description

The feature dataset containing the terrain is logically tiled, in its entirety, to form the tile scheme with its origin in the southwest corner. Tiles are square. Row and column numbering starts at base 1. The data area of the terrain may not fill the extent of the feature dataset so it's possible that only a subset of rows and columns are involved. This method provides the info about those tiles overlapping the terrain extent.

The returned row and column numbers represent the rectangular subset of tiles that intersect the terrain extent. Row and column numbering start at base 1 with the first row and column being in the southwest corner of the feature dataset.

The xmin and ymin are the real world coordinates for the lower left corner of the origin tile of the terrain.

The tilesize is the horizontal length of one of the square tiles and is equal to that specified when the terrain was created.
