performing, by the one or more computing devices, optical character recognition to identify the address;

determining a current location of the portable electronic device; and

generating directions from the determined current location to the identified address.

16 . The method of claim 15 , wherein determining a current location comprises using GPS to identify a current location for the portable electronic device.

17 . A method comprising:

capturing an image of a first street sign at an intersection using an image capturing component of a portable electronic device;

capturing an image of a second street sign at the intersection using the image capturing component of the portable electronic device; and

determining, by one or more computing devices, a location of the portable electronic device based on the images of the first and second street signs.

18 . The method of claim 16 , further comprising:

performing optical character recognition to identify a first street name from the image of the first street sign; and

performing optical character recognition to identify a second street name from the image of the second street sign.

19 . A method comprising:

capturing an image using an image capturing component of a portable electronic device that includes one or more computing devices;
