EPSG:18022

Sud Algerie

Attributes

Data source: EPSG

Revision date: 2012-04-18

Scope: Engineering survey, topographic mapping.

Remarks: Use with Nord Sahara 1959 datum. INCT uses this projection to the southern limit of Algeria but due to distance from origin OGP does not endorse this practice and south of 31°30'N recommends use of UTM.

Method: Lambert Conic Conformal (1SP)

Area of use: Algeria - 35 grads to 38.5 grads North (31°30'N to 34°39'N).
