Here is kind of a Hack for Google Maps where you can zoom more than the max zoom extent. Somple… small change in the url of the map and then you go a lot more closer. Amazing… also this works only for selected locations only. Check if your location is a Google Mega Zoomable Spot?

After the Hack

Here is how it works

Select a location and switch to satellite view. Zoom in as far as you can, and click ‘link to this page’ at the top right. Now replace the ‘z’ parameter in the URL with a higher value, e.g. 20, 22, or 23, and wait. Some locations will now show more detailed imagery.
