First …..Congratulation for this magnify project.

I’m evaluating Gmap to routing fire trucks in a google map.

The gps truck use old UTM coordinates, Zone 30, ed50, EPSG:23030.

How can I convert this coordinates to Google coordinates WGS84.

Something like this:

283539, 4821745, 30 >-----> 43.65456565, -5.6787878

 I try to adapt this code but fail:

 public void FromCartesianTGeodetic(double X, double Y, double Z, out double Lat, out double Lng)

 Is possible using gmap library?

Many thanks and sorry for my bad English.

Hi jcferalva.

I have tried the dotspatial library but my region (Cape Town, South Africa)  doesn't transform well.
The zones for my convertion is Hartebeesthoek 1994 ( EPSG: 2048) to WGS 1984 (EPSG: 4326).

I tried everything but found nothing that works.
I stubled apon a company eye4software that has a GPS toolkit made especially for this.
It costs EUR 149 and it can even read a GPS unit for its info.

PM me if you need code samples.
