google maps tiling scheme index grid
I have a need to cut tiles from a raster with bounds that result in no
partially filled tiles at a particular zoom level (no transparency or
black/white areas). First thought was to overlay an index grid so I could
see how to cut the raster. Is it possible to find shapefile or other
description of the tiling grid for google maps or other tiling schemes.
Also interested in other idea for achieving this goal. One is to simply
programmatically discard tiles with empty areas after the fact. Interested
in other suggestions as well.
