Equidistant Cylindrical

One of the oldest projections known, probably developed by Eratosthenes around 200 BC, its use is limited today. It is neither conformal nor equal-area, meridians and parallels are equally spaced straight lines.

This projection is supported in the spherical form only.

Note: This projection is also known as the Equirectangular Projection or Rectangular Projection

When the reference latitude of this projection is set to zero (i.e., equator) the result is equivalent to what is known as the Plate Carree Projection or Simple Cylindrical Projection

When the reference latitude is set to 45 degrees (north or south), a Gall Isographic Projection results.
