Verify if a point is Land or Water in Google Maps

Question

..and then Google-maps \"divide the waters from the waters\"

Well, not in the biblical sense but..

I would like to know what options I have in order to verif

Answer 1

This method is totally unreliable. In fact, the returned data will totally depend on what part of the world you are working with. For example, I am working in France. If I click on the sea on the coast of France, Google will return the nearest LAND location it can "guess" at. When I requested information from Google for this same question, they answered that they are unable to accurately return that the point requested in on a water mass.

Not a very satisfactory answer, I know. This is quite frustrating, especially for those of us who provide the user with the ability to click on the map to define a marker position.
