EPSG:30177

Remarks: Parameter values from Tokyo to JGD2000 (1) (code 15483). Assumes JGD2000 and WGS 84 can be considered the same to within the accuracy of the transformation.

Scope: Cadastre, engineering survey, topographic mapping (large and medium scale).

Remarks: Although legally defined as Tokyo datum the accuracy of the geodetic connection to mainland Japan is low. Replaced by JGD2000 / Japan Plane Rectangular CS XVII (code 2459) from April 2002.
