[OSGeo Africa] CRS in use in South Africa

[Lebogang Modiba]

Hi Peter

The coordinates on the sg diagrams and general plans helps us alot
especially in cases where the CSG spatial data recived from CSG offices are
incomplete or somwtimes incorrect.We use those coordinates to update and
validate  the cadastral data.
There are times where you find that the whole township is missing from CSG
spatial data and you require to work on that township urgently therefore
waiting for CSG officials tonot update it for u  not being an option.We use
those coordinates to plot that whole township ourselves either using auto
cad or ArcGIS.

I would request that there be education in helping GIS personnels in
converting those coordinates into decimal degress rather removing them.

Kind regards
Ms Lebogang Modiba
