I wonder is it possible to get coordinates (of pins) from Google Map which is integrated in some website?

It would be helpful to the community if you provide an example website in which you are interested in data-mining these coordinate(pins) locations. – Michael Markieta Jan 27 '12 at 11:59
@MichaelMarkieta, for example maps.google.com! It has always been a problem to get the coordinates from there! – Tomas Jan 27 '12 at 15:33
@Thomas can you check my answer to see if this is helpful. There are times when a google map has been created using the api and there are markers on the map which you want information about. Instead of trying to right click on ever marker, we can check each markers source code location. – Michael Markieta Jan 28 '12 at 17:58

View the page's source code and see if they are being publicly published. For example: http://www.canada411.yellowpages.ca/search/si/1/mcdonalds%20restaurant/Toronto%2C%20ON?showDD=true

If you view the source code on that page, you will be able to find the lat + long of each pushpin marker on the google maps map. Also, each record holds information about its lat + long regardless of it being shown on the map itself. Each webpage will be uniquely formatted. Some poking around in the source code may reveal a lot of information about the data to the user!

Near the bottom of the source:

    pushpinLocals[0] = new Array();
    pushpinLocals[0][0] = 43.732648;
    pushpinLocals[0][1] = -79.404175;
    pushpinLocals[0][2] = "<a href=\"javascript:getListingLink(1)\"  style='font-weight: bold;'>McDonalds Restaurants Inc</a>";
    pushpinLocals[0][3] = "3400 Yonge";
    pushpinLocals[0][4] = "Toronto, ON, M4N2M7";
    pushpinLocals[0][7] = "<br /><b>416-481-8779</b>";
    pushpinLocals[0][8] = customIconSpecification;

That is the right solution. I entered in the source code and find all coordinates I need. Thank you. – againstflow Jan 28 '12 at 11:22

Within Google Maps, right-clicking anywhere and then clicking "What's here?" on the contextual menu should return coordinates for the spot you clicked.

Yes, or "Drop LatLng Marker" on context menu. (+1) – CaptDragon Jan 27 '12 at 16:26
