Virtual sightseeing on Google Earth has become popular and there are many websites which publish KML files to show tourist attractions on Google Earth. It's a great experience that users can fly to and enjoy all famous and spectacular sceneries instantly, economically and environment-friendly. However, all main stream media (televisions, radios, newspapers and magazines) without hyperlink capabilities are rarely active in publishing the exact location information for all these natural wonders and historical sites due to the inefficiency of the longitude/latitude coordinates - the only way currently supported on Google Earth to represent any given location on the earth.

Now NAC Earth has solved this problem, and users can simply input a short Universal Address (such as H5Q2 R48Q) to get to any scene in the world (such as Eiffel Tower in Paris) as they want immediately on the NAC Enhanced Google Earth. A Universal Address is an eight or ten character NAC which can be used to represent both an area and a location anywhere in the world. A two character NAC can specify any area about 1000 km in length and width like a province, a four character NAC represents a 30 km long and wide area like a city approximately, a six character NAC is roughly equivalent to any square kilometer area on the earth, an eight character NAC can uniquely identify every house or building in the world, and a ten character NAC can pinpoint any location in the world to the resolution of one meter.

With the Natural Area Codes, people can easily represent any areas and locations, from countries, provinces, national conservation parks, cities, stadiums, museums, universities, hospitals, shopping malls, railway stations and docks to hotels, restaurants, post offices, street lights, fire hydrants, sewage exits, electric wirepoles and trees, and from locations of crimes scenes, accidents, pollutions, underwater wreckages and news events to locations of your dating benches, BBQ tables, camping sites and fishing spots. There are already many NAC enhanced products and services available such as:

• Locamagic - a NAC enhanced GPS cellphone application providing positioning, locating, navigating, local business searching, real-time tracking and real-time monitoring services.
• Universal Addresses Lookup Service and Free Geocoding Service providing Universal Addresses for any locations in the world.
