Co-ordinate Conversion - Plane (Y, X) to Geographic (Lat, Long)

This Service allows for the conversion of Plane (Y, X) Co-ordinates to Geographic (Latitude, Longitude) Co-ordinates using the Gauss Conform system as employed in South Africa with parameters for the WGS84 ellipsoid. This Service now supports the new Point Memory function that enables you to save points for further use on this Website during this Session. (Saved data will be lost when this window is closed)

This could be useful for conversion of GPS receiver co-ordinates. Although high relative accuracy is obtained between converted co-ordinates, a small transformation might still be needed to get a better local fit where the group of co-ordinates will be applied.

Just as an indication, Geographic Co-ordinates with Seconds specified to an accuracy of 4 decimal places normally yields Plane Co-ordinates with an accuracy of around the centimetre level (2 decimal places of a meter).
