Question

Hi

I want to use the Position class to transform between cartesian and geodetic coordinates on the Belgian ellipsoid. This ellipsoid (International 1927) is not defined in GPSTk, so how can I perform this conversion?

Answer

I created a new headerfile BD72Ellipsoid copied from GeoidModel^? and replaced the values by those valid for the the national datum (in my case, Belgium Datum 1972). When setting a position I use this BD72Ellipsoid model (in calls to setGeodetic and setGeoidModel). Conversion is performed OK
