Description (last modified by )
I need to project maps in South Africa, where we use the Hartebeesthoek projections. These are based on transverse mercator south orientated.
These projections are not supported, making it impossible for me to carry out any measurements etc. This effectively makes the application useless in most cases where such projections are needed.
It appears to be related to the fact that proj4 lacks support for south orientated projections.
Is there some way around this? Is there a solution using PostGIS, perhaps? If so, it should be highlighted for new users, with clear instructions on how to implement it.
Lastly there are quite a number of South orientated coordinate reference systems included with the QGIS database and it certainly does support them.
Regards
Tim

Hi
You can define custom projection definitions using the tool provided under the tools menu. Also your terminology is I think incorrect - Hartebeeshoek is a datum describing the spheroid. AFAIK Surveys and Mapping began phasing out the use of the Hartebeeshoek datum around 9 years ago, in favour of the WGS84 datum.
