With Natural Area Coding System, 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 to show the location on a map, use the the prefix 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 and its surrounding areas of our earlier office because an eight character NAC: 8CHK Q87P uniquely represents an area of 25m x 34m on the earth. How efficient NAC is!

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

  1. Using one unified format of coordinates to represent a three-dimensional region, a two-dimensional area, a line section and a geodetic point anywhere in the earth, on the earth, around the earth and even far away from the earth. As a location is just a special case of an area or a 3D 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, NAC can use the same format to represent all of these objects.
  2. Employing 30 characters instead of ten digits and making full use of these characters to construct the Natural Area Codes to make them very short, requiring only 50% of the number of characters required by traditional geodetic coordinates such as latitude/longitude coordinates.
