EPSG:15301 DEPRECATED

American Samoa Lambert

Attributes

Data source: EPSG

Information source: US National Geodetic Survey (NGS)

Revision date: 2004-08-09

Scope: Engineering survey, topographic mapping.

Remarks: Per Snyder: Map Projections - a Working Manual: At origin x=500000 ft; y=0 but radius to latitude of origin = -82000000 feet. Thus False Northing = 312234.65 ftUS. NGS confirms value of FN, which is encoded within their algorithms but not published.

Method: Lambert Conic Conformal (1SP)

Area of use: American Samoa - onshore and offshore.
