If you use Geolocation in your application, it may be useful to simulate being in a different location. Chrome allows you to do this by going to the "Settings" menu and selecting the "Overrides" tab. Within this tab it is possible to simulate a different latitude and longitude, and it is possible to simulate a geolocation being unavailable.

You can obtain the longitude and latitude of a location from Google Maps by enabling the LatLng tooltip on the Google Maps Labs page.
