EPSG:3989 Katanga 1955 / Katanga Gauss zone D
Projected system (Transverse Mercator) in use: Congo DR (Zaire) - Katanga west of 25.5°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.
