Hi Egg

Thx for ur effort in helping me out.I dont know what type of map im using eg. Mercator projection or something else.

But I will give you the site path from where I obtained the Map.

http://www.mapsofindia.com/maps/tami...hennai-map.htm

If u can see that and find what type it is then probably you will be able to clarify me better.

Regards
Vijay
