Gets the projection used by the CRS.
Gets the transformation used by the CRS.
Translates the given geographical coordinate
to a cartesian point at the given zoom level.
The coordinate to be translated.
The zoom level.
The cartesian point corresponding to the given coordinate.
Translates the given cartesian point to a
geographical coordinate at the given zoom level.
The point to be translated.
The zoom level.
The geographical location of the point.
Returns the scale used when transforming projected coordinates into
pixel coordinates for a particular zoom. For example, it returns
256 * 2^zoom for Mercator-based CRS.

Returns the distance between two geographical coordinates.
The first geographical coordinate.
The second geographical coordinate.
The distance between two geographical coordinates.
Serves as the base for CRS that are global such that they cover the earth.
Returns the distance, in meters, between two geographical coordinates.
The first geographical coordinate.
The second geographical coordinate.
