I sometimes need to publish data in Gauss-Kruger zone 3 and was wondering why there are now the following EPSG Codes which define this CRS.

  1. 31467 - DHDN / 3-degree Gauss-Kruger zone 3
  2. 31463 - DHDN / 3-degree Gauss zone 3

The Parameters are identical. Then why 2 Codes?

EPSG:31463 seems to be deprecated and EPSG:31467 is the correct one.

http://spatialreference.org/ref/epsg/dhdn-3-degree-gauss-zone-3/ is stating:

ProjCRS related to inappropriate coordinate system resulting in incorrect axes and name. Use EPSG:31467 instead.

you can see see this, if you compare the AXIS definitions:

PROJCS["DHDN / 3-degree Gauss zone 3 (deprecated)",
GEOGCS["DHDN",
    DATUM["Deutsches_Hauptdreiecksnetz",
        SPHEROID["Bessel 1841",6377397.155,299.1528128,

    I need to add spatialreference.org to my list of places to look for EPSG codes. Thanks. Although epsg.io hides it under the "deprecated" link. – Spacedman Sep 28 '18 at 7:04

    EPSG-registry is still the authority and it reports one more version of axis order and labels epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::31467 AXIS["northing (X)",north,ORDER[1]], AXIS["easting (Y)",east,ORDER[2]], – user30184 Sep 28 '18 at 9:23

    Note on EPSG registry: To look at "deprecated" objects, you have set up a login. It's only used send you notices of new versions. – mkennedy Sep 28 '18 at 18:12
