Guam 1963 / Yap Islands

Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Method: NADCON

Grid Files: guhpgn.las guhpgn.los

Remarks: Parameter files are from Guam 1963 to NAD83(HARN) (1) (code 1068), but for many purposes NAD83(HARN) can be considered to be coincident with WGS 84 within the accuracy of the transformation.
