This release adds a new feature and corrects an immediate bug that we encountered with the v1.1.6 release earlier today.
- The new sorting of points with timestamps was not working correctly with containers such as ordered sets, which is used in the comparison algorithm. We corrected this by introducing a sorting operator specifically meant for the sorting on import.
- We introduce a new feature "warp detection" that can remove large outliers that can occur when there is a jump from one point to another within a blink of time, for example, traveling a distance of 200 meters but the timestamp is the same for both points. We use a very high default speed detection of 1500 km/h as we don't know of any vehicle on ground that can go faster and because our candidate adoption feature takes care of outliers itself already. But the less outliers, the better the results, especially when the outliers are plain obvious. This feature is primarily meant to remove points with duplicate timestamps, especially when they are not in the same geopositions. But it can also remove points that have a different timestamp but a respective too high travel speed between the points. This feature is on by default but only is applied when a valid time information is provided with the track.
- The new time point sorting and the new warp detection feature showed some errors in our floating-car-data ground truth data. Therefore, we corrected the errors that we found and upload the corrected data in this repository now. It should be used instead of the old data from the linked zip file. However, the OSM data from that zip file is still necessary.
