[OSM-dev] "accuracy"

[Bernhard zwischenbrugger]

Hi

OK 10m.
If it's more than 10m I stop recording and start a new track if signal 
is ok again.
Here I can just walk around the block. I'm still sitting here in Phnom 
Penh with bad
med. disc <http://www.dict.cc/englisch-deutsch/disc.html> prolapse 
<http://www.dict.cc/englisch-deutsch/prolapse.html> and can't test 
(walk,ride,drive) that much.

I will set the accuracy to 100000000m for testing and then change it to 
10m for
visitors.
