Bug report #20624

remove redundant CRSs

Added by Gavin Fleming over 5 years ago. Updated almost 5 years ago.

Category:Projection Support

Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:up/downstream
Crashes QGIS or corrupts data:No Copied to github as #:28444


New CRSs for South Africa appeared in QGIS 3.

So-called EPSG:120480-102489 and EPSG:102562-102568 are not even in the EPSG registry, so where did they come from and why are they assigned EPSG authority?

They are completely unnecessary and redundant as 120480-102489 are already covered by the official EPSG:2046-2055 CRSs and 102562-102568 are already covered by the QGIS 'ZANGI' CRSs.

If they were added to QGIS, please remove them. Else if they come from proj.4, please indicate that so we can raise an issue with proj.

IDs above 100000 used to be user-defined in QGIS. But GDAL also uses them above CRSes come from https://github.com/OSGeo/gdal/blob/master/gdal/data/esri_extra.wkt. QGIS doesn't originally have them, but crssync adds them on install from GDAL (I guess also in 2.18).

#2 Updated by Giovanni Manghi over 5 years ago

  • Operating System deleted (MacOS)

102*** are usually CRSs from ESRI


but I can't find this ones listed as part of their list.

#3 Updated by Nyall Dawson almost 5 years ago

  • Resolution set to up/downstream
  • Status changed from Open to Closed

With QGIS 3.8 and the release of proj 6 library, any remaining projection definition related issues now should be filed with the proj project.
