transverse plate carrée
Aspects of: plate carrée
Geocart menu class: Cylindric
Transverse aspect of Plate Carree
Central meridian, each meridian 90° from central meridian, and the Equator are straight lines. Other meridians and parallels are complex curves, concave toward the central meridian and the nearest pole, respectively.
Poles: Points along the central meridian
Symmetry: About any straight meridian or the Equator
True along the central meridian and along any straight line perpendicular to the central meridian
Increases with distance from the central meridian, along a direction parallel to the central meridian
Function of the distance from the central meridian. No distortion occurs along the central meridian, but there is both area and local shape distortion elsewhere.
Conceptually projected onto a cylinder tangent to the globe at the central meridian
Can be compressed north-south to provide a Transverse Equirectangular projection, but rarely done
Topographic mapping (ellipsoidal form) of British Isles before the 1920s; replaced by the Transverse Mercator
Topographic mapping of a few countries currently
Developed by Cesar Francois Cassini de Thury (1714-1784) for topographic mapping of France in the middle 18th century
