Hi there everyone!
I managed to get the complete map of my town, and Nick Black kindly
converted it into OSM format (it was originally in Mapinfo format.
The problem is that my GPS arrived 2 days ago, and I collected some
tracks, just to find out that the Mapinfo map (and its OSM version)
were with a different, unknown datum.
Is there a way I can convert my OSM version to the WSG84 datum, using
my tracks as reference? Someone did it for a Garmin project, so it
probably is possible - I just don't know which tools to use.
Doing so would greatly save time, as almost all streets of my town, a
300.000 inhabitants one, is there - the only work needed would be to
correct names, tagging them accordingly to OSM and correcting some
directions, etc.
Cheers,
Francis
