EPSG:3396 PD/83 / 3-degree Gauss-Kruger zone 3

Projected system (Transverse Mercator) in use: Germany - Thuringen - west of 10.5°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.
