EPSG:3295

Guam 1963 / Yap Islands

Available transformations
to EPSG:4152
EPSG:4152 - NAD83(HARN)

Selected transformation

Method: NADCON

Grid Files: guhpgn.las guhpgn.los

Remarks: NADCON method which expects longitudes positive west; EPSG GeogCRSs Guam 1963 and NAD83(HARN) (codes 4675 and 4152) have longitudes positive east. Can be used as approximation for tfm between Guam 1963 and WGS 84 - see tfm code 1069.
