let me rephrase that: since Mumbai data is skewed, when mapping any area the 
first job is to realign the streets. Naming is more or less ok, but the streets 
are out of place. The Yahoo satellite imagery may be relied on as on testing 
with GPS in various parts of Mumbai, it is accurate. However due to heavy tree 
cover in many parts, it is difficult to trace without GPS tracks.
