The present invention provides a method, the QCODE method, of geotagging all postal addresses and other points of interest that one might want to navigate to and which allows the user to identify these addresses and other points of interest with a code consisting of 6 alphanumeric characters or less. A point of interest may or may not have a street address, for example, “the main entrance to the Jefferson Building at the USPTO complex in Alexandria Virginia” or “the entrance to the VIP parking area at Yankee Stadium”. The disclosure teaches embodiments that are naturally upgraded to integrate changing spatial information due to addition of countries, better data, political changes, and other similar changes in geographical data. A single geocoding engine is capable of handling the various address formats in use in different countries and jurisdictions.
