Hi Gerd, I have done some comparison between trunk r3057 and high-precision r3065. Routing is very similar. I have found some examples, where calculated route was a bit different, but both versions have looked correct. I have found one example, where BaseCamp hasn't been able to calculate short route for r3057 but the same route has been calculated correctly with r3065. For above tests I have used map of Poland, some longer routes across whole country and some routes inside a city. I have done another test with map of Europe and r3065 only. BaseCamp can successfully calculate very long routes, like for example Viena-Madrid, Hamburg-Naples or Murmansk-Sofia. I can't say, if this is due to recent changes, but this is very distinct progress since the last time I have tested it. My congratulations to all developers. -- Best regards, Andrzej
