The '''equirectangular projection''' (also called the '''equidistant cylindrical projection''' or '''la carte parallélogrammatique projection'''), and which includes the special case of the '''plate carrée projection''' (also called the '''geographic projection''', '''lat/lon projection''', or '''plane chart'''), is a simple [[map projection]] attributed to [[Marinus of Tyre]], who [[Ptolemy]] claims invented the projection about AD 100.<ref>''Flattening the Earth: Two Thousand Years of Map Projections'', John P.
