The openstreetmap data for mumbai is bad afaik.
Sorry for going off-topic, but what map? what device? I want to know with extreme eagerness.
gps device used for mapping the area around HBCSE during the openstreetmap workshop, several of which were held in the country by the FSF and friends with Schyuler Erle and Mikel Maron last month.
The map data donated by AND corp for mumbai is randomly inaccurate, thus requiring people to go into the streets with a gps logger (fat plug - one such i happen to make and sell), collecting coordinates and using a combo of your collected data, yahoo imagery and maybe AND data to generate accurate stuff.
BTW the personal navigation devices (with data) being sold here claim 70% accuracy. God help you with that.
For the record even google maps data is wrong in most places, with gps data, street maps and satellite imagery producing three different results.
