OK, I just released v3.5.2 which will detect single-point GPS ‘spikes’ seen in the data stream of some dashcam models. If a point is more than 5 km apart from its neighbors, then the point is discarded and replaced with an interpolated point.
Here is an example of how the spike reduction works. Shown below are images from the Dashcam Viewer map view. The top two images are from an INNOVV K2 and the bottom two are from a Viofo A129 Duo (apparently this issue isn't limited to just one manufacturer). In the top images, the transient was caused by a single out-of-scope point, and was eliminated by the algorithm. In the bottom images, the single spikes were removed but spikes caused by two or more consecutive points were left alone. In this case it's a good idea bring the issue up with the manufacturer rather than rely on the viewer software to patch the issue.
Version 3.5.2 reduces and/or eliminates random data spikes seen in some dashcam models’ GPS data. Instances where two or more consecutive points are out-of-scope are not massaged.
