Thanks a lot, what a perfect response, i am blown away. This will help a lot.
I opened your gpx Track on https://gpx.studio/, it worked great, then i imported it into my DMD2 app, also worked liek a charm, i even was able to see all individual tracks.
When you say you need to inform, how is that been done? Do I call someone, go somewhere, ask someone, is it online? How do you now where it is reuired to get permission?
