EPSG:4572 New Beijing / Gauss-Kruger zone 17

Projected system (Transverse Mercator) in use: China - 96°E to 102°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.
