The Equidistant Cylindrical projection is probably the simplest of all map projections to construct, and one of the oldest. Meridians and parallels are equidistant straight lines, intersecting at right angles. Poles are shown as lines. This projection is used only in spherical form. If the Equator is made the standard parallel, true to scale and free of distortion, the meridians are spaced at the same distances as the parallels, and the graticule appears square. This form is often called the Plate Carree or the Simple Cylindrical Projection.
The "Equidistant Cylindrical" projection has the following parameters:
-
False Northing
-
False Easting
-
Longitude of natural origin
-
Latitude of 1st standard parallel
