EPSG:10250 S34S reconstruction east-orientated

Projected system (Transverse Mercator) in use: Denmark - onshore Zealand and Lolland. 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.
