Edit tracks and documentation about the mtrack format #185
-
|
Hello, I have quite often the need that I want to edit the finished track. Mainly to remove some captured waypoints, either because of a GPS error or because I forgot to turn off the mapping while I was already driving home. How could I go about this? I assume this is currently not possible within Trekarta, or even within the scope of the application? Related to that, is there some documentation on the mtrack data format? I couldn't really find information on it, so I assume it is a self-made format. Is it possible to edit the data outside Trekarta? Kind regards, Simon |

No, this is not possible, nor I can think of any easy and usable way to do this. You always can export track to GPX or KML format and edit it on PC. mtrack is a binary format using Google protobuf (pbf) encoding. The schema can be found here: |
