I have some incomplete GPS recordings. For whatever reason, the tracks weren't recorded , so there are some gaps in it. I could easily use the satellite images using QGIS software.
So I would like know how can I get them in order to alter an recorded GPX tracks without losing the timestamps. I want to:
- add tracks (track points)
- split tracks
- merge tracks
add timestamps to manual added tracks/ track points based on the original ones
snaps tracks / track points to features (mainly roads) in osm or google maps.
- export the altered records so that geosetter can read them flawless.
