Hello ! One think I think it can be useful is a tool for editing all our old trace : - easy to download all our trace - easy to remove unprecise segment (in some old my trace I have some segment who is 50 m wrong !) - easy to simplify them - easy to re-upload modified trace !
I think that a tool like it can be greatly improve the quality of traces. CU Stéphane Liz a écrit : > On Tue, 28 Jul 2009, Simone Cortesi wrote: >>>> Does OSM invalidates GPS data after some time?
