washingtonDC :: Point Source #

For use as a reference point in certain projections.

craig :: Point -> Projection Source #

Craig retroazimuthal projection (works on a subset of the world)

winkel3 :: Projection Source #

Winkel Tripel projection (standard for the National Geographic Society since
