title: 'tilemath: Tile Math for Map Tile Pyramids'
version: 0.0.0.9000
abstract: 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.
