EPSG:10254 S45B reconstruction east-orientated
Projected system (Transverse Mercator) in use: Denmark - onshore Bornholm. 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.
