Origin is at intersection of equator and Greenwich meridian. Note: this is not the same as plotting unrectified graticule coordinates on a computer display using the so-called pseudo Plate Carrée method: here the grid units are metres.

Equidistant Cylindrical (Spherical)
See method code 9842 for ellipsoidal development. If the latitude of natural origin is at the equator, also known as Plate Carrée. See also Pseudo Plate Carree, method code 9825.
Note: These formulas have been transcribed from EPSG Guidance Note #7-2. Users are encouraged to use that document rather than the text which follows as reference because limitations in the transcription will be avoided.
This method has one of the simplest formulas available. If the latitude of natural origin (latO) is at the equator the method is also known as Plate Carrée. It is not used for rigorous topographic mapping because its distortion characteristics are unsuitable. Formulas are included to distinguish this map projection method from an approach sometimes mistakenly called by the same name and used for simple computer display of geographic coordinates ? see Pseudo Plate Carrée (coordinate operation method code 9825).
For the forward calculation:
X = R . (lon - lonO) . cos(latO)
Y = R . lat
where R = ((a^2 * (1 ? e^2)) / (1 ? e^2 sin^2 latO)^2)^0.5
and latO, lonO, lat and lon are expressed in radians.
For the Equidistant Cylindrical method on a sphere (not ellipsoid), e = 0 and R = a.
For the reverse calculation:
lat = Y / R
lon = lonO + (X / R cos(latO))
where R is as for the forward method.

The latitude of the point from which the values of both the geographical coordinates on the ellipsoid and the grid coordinates on the projection are deemed to increment or decrement for computational purposes. Alternatively it may be considered as the latitude of the point which in the absence of application of false coordinates has grid coordinates of (0,0).

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Easting, FE, is the value assigned to the abscissa (east or west) axis of the projection grid at the natural origin.

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Northing, FN, is the value assigned to the ordinate (north or south) axis of the projection grid at the natural origin.
