EPSG:4541 CGCS2000 / 3-degree Gauss-Kruger CM 96E
Projected system (Transverse Mercator) in use: China - 94.5°E to 97.5°E. 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.
