Cassini projection
From Wiki.GIS.com
The Cassini projection is a transverse cylindrical map projection that maintains scale along the central meridian and all lines parallel to it, and is neither equal-area nor conformal. It is best suited for large scale mapping of areas predominantly north-south in extent and areas near the central meridian, however the Transverse Mercator projection is often preferred because of the difficulty measuring scale and direction in Cassini.
Since the scale is constant along any straight line on the map that is parallel to the central meridian, the projection is more suitable for regions that are north-south in extent than for regions extending in other directions. Formerly used by the Ordnance Survey in Great Britain, Cassini is still used in Cyprus, Czechoslovakia, Denmark, Germany, and Malaysia.[1]
