Hi Guys, The precision on the N95 internal gps is not good, but with an external bluetooth gps device it is somewhat better. I am one of the developers of motortrace.com, which is a vehicle tracking solution, and one of the things we currently offer is phone tracking software. This is a free j2me midlet which takes the position of the phone every x seconds and/or every x meters (configurable), and stores it on the phone. It can be uploaded to our website (http://www.motortrace.com) for further processing, or simply exported as a gpx file.
I was hoping to support OSM much more in the upcoming months, and would like to add waypoint etc functionality to the midlet. Regarding covering multiple paths: our main business is vehicle trackers, and these cover the same path many times on a regular basis all over a number of countries. I would be interested in importing this data to OSM in areas where data is poor. The average speed of the vehicles might give a heads-up for the type of road etc. Cheers, Andy Igor Brejc wrote: > Nick Whitelegg wrote: > >> Hello everyone, >> >> Have managed to got hold of a N95 for research purposes through work.
