[Talk-in] Coastline changes at different zoom with yahoo map

[Kenneth Gonsalves]

you need to check it with gps tracks - for example, the coastline  
around Mangalore is accurate, but around Mumbai is offset. I have  
found that both in Mangalore and Mumbai the gps tracks and the  
satellite image coincide
