xRoute2: how to gather magnetic via points (geodecimal) from a BCR (mercator)
Posted: Tue Aug 29, 2023 7:58 am
Cheers,
these days a partner asked me how he can gather meaningful (x,y) geodecimal coordinates from a PTV xServer2 request which is based on geodecimal coordinates. He requires them to feed some external navigation system for some guided navigation. As you may know we return a so-called BCR text aka RouteResponse.guidedNavigationRoute
So here's what you need to know to transform them into geodecimal:

This text contains the desired coordinates but these are based on PTV Mercator - no matter what the underlying route request's coordinate format is.[CLIENT]
