# Cylindrical Equal Area

Name | Cylindrical Equal Area Alias | Normal Authalic Cylindrical (FME)

Alias | Gall Orthographic (standard parallel = 45)
Alias | Peters (approximated by Gall Orthographic)
EPSG Code | -
GeoTIFF Code | CT_CylindricalEqualArea (28)
OGC WKT Name | Cylindrical_Equal_Area
Supported By | OGC WKT (unofficial), PROJ.4, Mapinfo

### Projection Parameters

Name | EPSG # | GeoTIFF ID | OGC WKT | Units | Notes Central Meridian |  | NatOriginLong | central_meridian | Angular |
Standard Parallel |  | StdParallel1 | standard_parallel_1 | Angular | Defaults to zero.
Known as latitude of true scale in PROJ.4 False Easting |  | FalseEasting | false_easting | Linear |
False Northing |  | FalseNorthing | false_northing | Linear |

### Notes

This is classified as a cylindrical and equal area projection, as one might expect from the name. There does not seem to be an EPSG equivelent. The GeoTIFF code was added Feb 2005, and so is not likely widely supported.

For documentation, the Cylindrical Equal-Area projection is discussed in Snyder, Map Projections -- a Working Manual (1987) on pg 76ff.
