EPSG:4201

Adindan

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Derived at 22 stations.

Information source: U.S. Defense Mapping Agency TR8350.2 September 1987.

Revision date: 2015-04-22

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: Adindan

Datum: Adindan

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: OGP

Information source: US Coast and Geodetic Survey via Geophysical Reasearch vol 67 #11, October 1962.

Revision date: 2015-04-22

Scope: Geodetic survey.

Remarks: The 12th parallel traverse of 1966-70 (geogCRS Point 58, code 4620) is connected to the Blue Nile 1958 network in western Sudan. This has given rise to misconceptions that the Blue Nile 1958 network is used in west Africa.

Method: Geocentric translations (geog2D domain)

Area of use: Eritrea; Ethiopia; South Sudan; Sudan.

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
