The Natural Area Coding System has been implemented in TravelGIS.com's map system. Now, you can conveniently retrieve maps with NAC and display a location on the map with NAC. For example, NAC: 8CHK Q87P is the location of our earlier office (50 Stephanie Street in downtown Toronto, Canada). You can type in the NAC and draw a symbol on a world map, then use NAC: 8 Q to get the map of the province, NAC: 8C Q8 to get the map of Toronto and NAC: 8CH Q87 to get the neighborhood of the location. All the maps will show the exact location of our earlier office because NAC: 8CHK Q87P represents a small area of 25m x 34m universally. How efficient NAC is!

The Natural Area Coding System is a new geodetic system developed by NAC Geographic Products Inc., which introduces two new features to the geodetic system:

  1. Using one unified format of coordinates to represent a three-dimensional region, a two-dimensional area, a line section and a geodetic point. A traditional geodetic point in fact is just a special case of an area or a region when the size is relative small, and a line section is just a special case of a rectangle when one of its side is relative small.
  2. Employing 30 characters instead of ten digits and making full use of these characters. Then the coordinates of the new system become very short, requiring only 50% of the number of characters that traditional geodetic coordinates require.

These two features make the Natural Area Coding SystemTM superior over traditional geodetic systems. Besides all functions of traditional geodetic systems, the new system generates an efficient global postal code system, an efficient emergency address dispatching system for all kinds of emergency services, a unified map grid system for all kinds of maps of all scales, a memory-saving and efficient geographic and geodetic information management system, a powerful navigation system for everybody to find locations and addresses anywhere in the world efficiently, a universal telecommunication address code system, a universal property identity code system, and a universal geodetic reference system for all sciences and engineerings related to the physical world. It unifies all these systems into one simple system and can greatly simplify the communication between different categories of science and engineering, different languages, and different countries.

At this site, you can find many NAC RELATED WEB PAGES, in which you may find the (longitude, latitude) of your own address, and using the obtained data you can run the programs to calculate your NAC or convert a given NAC to (Longitude, Latitude). There are a Frequently Asked Questions (FAQ) column where you can find answers to many questions you may have, and The International NAC Society, Inc. has been established by supporters to promote the system world wide.

If you have questions, suggestions or comments or you are interested in participating in the discussion of the NAC System and/or contributing to the promotion of the system, please send your message to: info@nacgeo.com. Thanks for the visit to this site.
