Could someone please explain (or point me to a place that explains) what the coordinate system for Wg23 (Hartebeeshoek Lo23) should look like on a map? There is a coordinate flip that constantly comes into play, when I work with WG23 data, which I don not understand. This gets even messier when working with a modified grid (e.g. a mine grid).
My first coordinate (Easting I assume?) is usually negative, resulting in map displays that are North down. Occasionally I would receive similar data sets with the North up. I'm not sure when and how this flip is applied and how I should correct for it.
I work in QGIS and ArcGIS.
