Hi, Thank you so much for your valuable inputs and guidance.

I checked few other mapped fuel stations here and found most of the fuel stations here were tagged only with single address point. Also most of the fuel stations in our country would be fully owned and operated by the gas companies which provides fuel and other free services ( Compressed Air or Nitrogen Refilling, Purified Water and Toilets). I believe covering the area with fuel station tag and describing toilets, water doctor and Compressed Air Dispenser with point tag separately inside the area would better define it.

Also thanks for letting me know about India talk-in mailing list. I am subscribed for it now :)
