> Please provide me with a test file that shows the problem.
This file has 5 points with the following characteristics:
- first two points compared have the same time, but a slightly different positions
- second two points compared have the same position, but 1 second difference in time
- last two points are normal points (different position and time)
Official version of RouteConverter (v2.10) reads this file as 4 points only with some points/data (time, elevation) lost and duplicated time on last two points. Even if you feed the official version with a simpler NMEA file, it will behave the same (1. point problem, last points duplicated).
Of course there are much more combinations of entries in NMEA files which I didn't test, but at least with this fix I can process NMEA files that I got hands on.
