Selected transformation

Name: American Samoa 1962 to WGS 84 (2)

Method: NADCON

Grid Files: wshpgn.las wshpgn.los

Remarks: Parameter files are from American Samoa 1962 to NAD83(HARN) (1) (code 1578), but for many purposes NAD83(HARN) can be considered to be coincident with WGS 84 within the accuracy of the transformation.
