EPSG:10285 ETRS89/DREF91/2016 / 3-degree Gauss-Kruger zone 3
Projected system (Transverse Mercator) in use: Germany - Hamburg. 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.
