Is there any way or example i searched about it on google and Site both but didn't get Anything

Sorry I've no Codes i want idea, code or something helpful.

Answer 1

A simple search yielded http://www.the-di-lab.com/polygon/ and you can find a lot more samples at http://code.google.com/apis/maps/documentation/javascript/demogallery.html.

Unfortunately the above demo is a minified js. But the essential part of drawing a polygon (area) on google maps is to 1. load the map 2. trap the click events and the position (lat/lon) 3. draw lines 4. Finally when a double click is received, close the polygon

I unfortunately do not have a ready made sample in hand.

The answers here are quite outdated. Google Maps now have a drawing library, This library allows the user to insert markers, circles, polygons and other types as well.

You can find an example on it here. And the library reference here. And the documentation here.
