EPSG:3316 Kasai 1953 / Congo TM zone 22
Projected system (Transverse Mercator) in use: Congo DR (Zaire) - 6th parallel south 21.5°E to 23°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.
