Hi prakash dhake
talk to your local surveyor. He will enjoy telling you, and you will make a useful contact.
He should talk about trig points which are accurately surveyed and clearly marked points (above mean sea level). You refer your local measurements to one of these trig points. I am told some GPS systems have this built in, but for accurate elevation work, a transmitter is located at a trig point and used to modify the GPS signal.

Cheers

Steve
