One other trick I use is to right click on the location on google maps, click "what's here?", and then the coordinates will pop up in the search bar. Copy those coordinates, and then I go over to Bing.com, maps, and paste the coordinates, enter, then click bird's eye view. This gives you a much lower aerial view, and you can rotate it with the arrows around the compass in the top right. I use this to find trails and shorelines to fish from. Depending on the angle of the photo and the lighting, you can find underwater structure this way too.
