I just discovered TrackMe a few days ago, so I am not an expierenced user.
Background: I want to track a comming several weeks holiday trip with my family with TrackMe and publish a live map on a website (Wordpress with Trackserver-Plugin) to give our Families&Friends the chance to see where we are
What I recognized yesterday is that the accurancy of the GPS is not always very good. Of course this is not a problem wihtin TrackMe, since it gets its information about the position from the GPS-module of my phone, but my question is as follows.
Example: I was at home an I was doing some tests with TrackMe setting like time base recording and minimum accuracy and minimum distance. This means I was at home all time, but we I look in the recorded positions then I see e.g. one position almost 300km away from my house. So this means that is is clearly a faulty position.
As I do not know/find any other setting filter/suppress such wrong positions in the track, I thought about an option similar but vice-versa to "minimum distance". Let´s call it maximum distance. If I know that I configured position recording to let´s say every 5 minutes, then I know that I cannot go more than 10km (assumed a velocity of 120km/h). In this case a filter mechanism could suppress every position that is more than 10km away from my last position.
- it could be possible to double the maximum distance, because if one positioning was erronous then the intervall between the first and the third (second erronous) position recording might be 10 minutes insteadof 5min (I do not know if it would be possible to directly retry to record a position if one was denied by this filtering, insteadof waiting for the next interval of e.g. 5 minutes)
- maybe it would be possible in a next improvement to make this filtering distance dependent on the (average) speed of the last few recoreded positions
These are just some ideas because these erronous positions within an track would be quite annoying and distance calculations and other statistics would be wrong. At least live tracking on a website would have very strange effects.
