Overview

This module contains utility classes for working with geospatial data.

It includes functionality for:

WGS 84-compliant coordinates
supporting tiling schemes, such as Web Mercator or HERE tile
supporting map projections, such as Web Mercator or Equirectangular
math utility functions for working with radians and degrees
