Yes, checked and understood that the syntax is very important (of course !). Thanks.
I wanted to do it, using the Route in Geomap but this option is not available in the menu. Is theresomething special to do ?
Here below a picture showing what I was able to do. Thanks to you.
But as you can see, the image quality is not “good enough” with the MapTrack3D visualization. That’s why I want to do it with Geomap.
And I would like to have a point at each extremity of the lines, points showing the related info (e.g. Aiport name, and/or city and/or date, …).
