%description
Impose a tiling scheme on a raster grid defined by its dimension and
extent. Computes tile counts, pixel offsets (suitable for spatial library
windowed reads), and geographic extents for each tile. Also supports
standard Web Mercator and geodetic tiling profiles with zoom levels, and
provides a spatial map of what each chunk covers for interrogating virtual
raster stores. Based on the analysis of Lamb (1994, ISBN-13:
978-0748403158) "Tiling very large rasters" in 'Advances in GIS Research:
Proceedings of the Sixth International Symposium on Spatial Data
Handling', volume 1, pages 449-461.
