Geodetic CRS: Bermuda 1957
Datum: Bermuda 1957
Ellipsoid: Clarke 1866
Prime meridian: Greenwich
Data source: EPSG
Information source: Department of Lands Buildings and Surveys.
Revision date: 2011-01-25
Scope: Transformation of coordinates at 1m level of accuracy.
Remarks: Derived in 1998 at 12 stations. Used for transformation of 1:2500 mapping. May be taken as approximate transformation Bermuda 1957 to WGS 84 - see code 15970.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Bermuda - onshore.
