tilemath: Tile Math for Map Tile Pyramids
Pure tile math for map tile pyramids. Provides coordinate conversions between longitude/latitude, Mercator metres, pixel coordinates, and tile numbers; quadkey encoding and decoding; TMS y-axis flipping; URL templating; and convenience helpers for selecting tiles from an extent or a point with automatic zoom selection. The default pyramid is web Mercator but the internal structure leaves room for longlat and arbitrary raster pyramids.
