My question relates to creating a custom CRS of the official coordinate system used in South Africa, called SACRS.
The SACRS is a projected coordinate system that must be referenced to BOTH the "Hartebeesthoek94" datum and the "Gauss Conform Coordinate System" (see help guides at the bottom of this post). I seek technical advice on creating this projected coordinate system as a custom CRS.
What should I type in the parameters box in QGIS (proj4 format)?
I am not sure if any of the following coordinate systems are already close (or similar) to the SACRS, but perhaps they are a good starting point for a custom CRS:
- Hartebeesthoek94 / Lo25 [EPSG 2051]
- South African CRS: HBK_NO_25 [ZANGI:ZANGI:HBKNO25]
