Great product and thanks again for supporting OpenStreetMap.

I am using MaemoMapper with an i-Blue BT-GPS to log tracks that I process with OSM. I use the OSM map repository to see what I have not yet tracked.

What I notice, is that the accuracy of the MM tracks is not always good. It is okay if you do long forward stretches, but tends to give a lot of bogus results when you take a lot of turns in cities (which I do a lot, because I want to track every street and every corner). Btw: I wait at every turn for the signal to stabilise.

What I am wondering is, is my GPS giving bogus results (due to buildings, sharp corners, etc.) or is MM doing some optimistic prediction when the signal is of less quality?

If so, would it be possible to switch prediction off and just track the points that are good (i.e. skip points where the signal is below a certain treshold?). This would make MM an even better tool for OSM track usage.

Best,
Zoran
