The Cassini projection is a cylindrical projection. It is neither equal-area or conformal. The central meridian, each meridian 90 degrees from the central meridian and the Equator are straight lines. Other meridians and parallels are complex curves. Scale is true along the central meridian and along lines perpendicular to the central meridian. Scale is nearly constant but not true along lines parallel to the central meridian.
The Cassini projection has been used for topographic mapping in England and currently in a few other countries.
