[QGIS-ZA-user] Hartebeeshoek L027

[Jordaan Fouche]

Hi Gavin I am on QGIS 3.16. I have looked for the Zangi and HBK projections but could not find it. I know they were in the earlier versions of QGIS, but don’t see them anymore.

Hi Jordaan

 

Have you tried the ZANGI CRS? I had some issues in the past and using this set of projections helped. 

 

CRS: South African CRS:HBK_NO_27

Auth Id: ZANGI:ZANGI:HBKNO27

Dear All

 

 

I am buy working on a project which is in  Hartebeeshoek L027 (EPSG 2052). It appears that all my data is transposed. 

 

Some of the vector data that I am importing has been exported from Arc, others are photo mozaics from the NGI, and others are SGO data, however every datapoint has been transposed. I.e. what should be plotting SW is plotting NE, and what should be plotting NW is plotting SE.

 

Has anybody encountered this problem before. I have corrected some of the data by exporting the geometry through MMQIS, then multiply the coordinates by -1 and, re-import to a WGS84 project. Then the data plots in the right place. But it is an helluva work around and it should not be like that. Or am I doing something wrong?

 

Jordaan
