EPSG:4577 New Beijing / Gauss-Kruger zone 22
Projected system (Transverse Mercator) in use: China - 126°E to 132°E onshore. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
