Returning a location for a device is accomplished by receiving a first image, captured by a device, and a first orientation of the device from the device over one or more networks. A second image, captured by the device, and a second orientation of the device is received from the device over one or more networks. A first location of a first object included in the first image and a second location of a second object included in the second image can be determined respectively from a database of object locations. A location of the device is determined according to the first orientation, the second orientation, the first location of the first object and the second location of the second object. The device location is transmitted to the device.
