What coordinate System can I apply to South Africa in GE Smallworld 5.1?The CS units should be in meters. 1.I understand that the datum used is 'hartebeesthoek_1994' , Is it necessary to create 'WGzones' from WG17 to WG31 as mentioned online?Can I create a single coordinate system for the entire country? 2.As Smallworld Doesn't support TM south based projection, I was wondering if I can apply Traverse mercator projection? If yes, what should be the parameters?

  • The EPSG dataset contains information about most, if not all, commonly used coordinate reference systems. Hartebeesthoek 1994 seems to be EPSG:4148, see spatialreference.org/ref/epsg/4184. But the 'WGzones' are also included in the EPSG dataset, e.g., EPSG:2072. – StevenLooman Sep 20 '16 at 15:16
  • Do you have the possibility to define a custom projected coordinate reference system? If so, duplicate the zone definition but make the scale factor -1.0. – mkennedy Oct 12 '16 at 12:43
