3 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. CURRENT PROBLEMS

4 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Geographic Coordinates Current geographic coordinates such as longitude/latitude and UTM They require long character strings to represent locations that are nearly useless to consumers They are defined on different geodetic datums that introduces huge amount of work in datum conversion They have many writing conventions and units such as decimal degrees, degrees/minutes/seconds, kilometers, meters, feet, etc that add more complexities in parsing and converting the coordinates

5 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Geographic Area Codes Currently, there are no universal area codes for all areas in the world. People have to use various non- standard and inefficient ways to specify areas such as: Names of places: countries, provinces/states, cities, etc that are language dependent and incomplete Postal codes and telephone service area codes that have different formats and do not cover all areas Map sheet numbers such as Canadian National Topographic System (NTS) map sheet numbers that are defined only in some countries.

6 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Addresses Current addresses in the world are Language dependent: written in hundreds of different languages Defined differently: different elements and different writing conventions Inefficient: consisting of long strings of characters of different languages Irrelevant to geographic coordinates

7 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Postal Codes Current postal codes used in the world have many problems too. They are different in different countries They are facing shortages in assigning new codes They are getting chaotic in spatial distribution They are not assigned to individual addresses They need to be maintained

8 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Map Grids Current maps use many different map grids: longitude/latitude, UTM and locally defined grids. The grid coordinates of these grids are difficult to be connected Locally defined grids on many street maps generate grid coordinates meaningless outside of their maps. Consumers cant directly pinpoint addresses on these grids

9 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. GPS Receivers GPS receivers can instantly tell its accurate location anywhere in the world. However, the representation of the location is a big problem Using street addresses to represent locations needs a huge address database which is always outdated and incomplete, and street addresses are not available in most locations and also very long language dependent character strings. Although geographic coordinates cover all locations, they are always too long to read, remember and communicate Using maps to display locations makes GPS receivers large, heavy, short battery life, expensive and complicated. It is still difficult to communicate the location information.

10 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. GIS and Mapping Because of the lack of efficient universal area codes, GIS and mapping software have to use geographic coordinates to specify an area and retrieve its map for a randomly given area, which needs four long decimal geographic coordinates that: Take long time to input Are very difficult to remember and communicate

11 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Huge Gaps The most serious problem is that there are huge gaps between location representations such as: Street addresses and geographic coordinates Street addresses and map grids Place names and geographic coordinates Postal codes and geographic coordinates Street address and postal codes

12 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. THE NATURAL AREA CODING SYSTEM

13 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Objective The objective of the new geodetic system is to standardize, optimize and unify Geodetic datums Geographic coordinates Geographic area codes Map grids Addresses Postal codes

14 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Approaches To reach the objective, the following approaches are taken: Unifying the concepts of geographic areas and geographic locations because any point can be represented by a small area Using more characters (the 30 most popular characters in the world) instead of digits to compress the representation 0123456789BCDFGHJKLMNPQRSTVWXZ Introducing a standard, highly efficient, flexible and unified representation for both an area and a location

15 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Definition The Natural Area Coding System is defined by a series of grids called NAC Grids to divide the world: Level 1 Grid: divide the world into 30 divisions in both longitude and latitude directions. Level 2 Grid: divide each cell on Level 1 Grid into 30 divisions in both directions. Level n Grid: divide each cell on Level n-1 Grid into 30 divisions in both directions, where n = 2, 3,.... Each division is assigned a NAC character accordingly.

16 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Representation – Simple NAC A Natural Area Code (NAC) is written in a strict format that starts with: NAC: followed by two character strings representing longitude and latitude respectively separated by a blank space, e.g. NAC: 8CNB Q7Z4 Where: 8 and Q represent Level 1 NAC Grid coordinates C and 7 represent Level 2 NAC Grid coordinates N and Z represent Level 3 NAC Grid coordinates B and 4 represent Level 4 NAC Grid coordinates

17 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Representation – Complex NAC A series of neighboring NACs forming a rectangular area on a NAC Grid can be written as a complex NAC. NAC: 8CNB Q7Z4 8CNB Q7Z4 8CNC Q7Z4 + NAC: 8CNC Q7Z4 + NAC: 8CNB Q7Z5 8CNB Q7Z5 8CNC Q7Z5 + NAC: 8CNC Q7Z5 = NAC: 8CNB-C Q7Z4-5 8CNB-C Q7Z4-5 With complex NACs, any randomly given area can be represented by a NAC

18 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. NAC Cell Sizes Each simple NAC represents a NAC cell in the world with an area approximately equal to: LEVEL Sample NAC AREA 1 NAC: 8 Q 1000x700 km 2 NAC: 8C Q8 33x23 km 3 NAC: 8CN Q8Z 1.1x0.8 km 4 NAC: 8CNB Q8Z4 35x25 m 5 NAC: 8CNBD Q8Z4H 1.2x0.8 m

19 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Efficiency in Representing Points A NAC can be used to represent any point location on the earth to save about 50% of characters compared with other geographic coordinates, and tells not only the location but also the resolution of the representation. The following represent the same location with the same resolution: NAC: 02CK7 7SPJJ Latitude South 43.05632, Longitude West 179.04567

20 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Efficiency in Representing Areas A NAC can be used to represent any area on the earth to save about 90% of characters compared with other geographic coordinates. The following represent the same area: NAC: 8G PW An area centered at Longitude West 78.2 degrees and Latitude North 41.5 degrees with a span of 24 minutes in easting and 12 minutes in northing

21 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. APPLICATIONS

22 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Universal Address An eight or ten character NAC representing an area about 25x35 meters or 0.8x1.2 meters anywhere in the world is called a Universal Address that can specify uniquely in the world: Each building Each houseOur address Each gate/door Each parking meter1608-45 Huntingdale Blvd. Each fire hydrantToronto, ON M1W 2N8 Each sewage exitCanada Each treeNAC: 8CNB Q8Z4 Each street light Each bus stopOur Universal Address

23 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Universal Address (contd) Compared with traditional addresses, the Universal Address has many advantages: Standard in the entire world Language independent Defined everywhere Easy to display, read, remember and communicate Fit small spaces of business cards, yellow pages, etc Pinpointed on all maps with Universal Map Grids Navigated with GPS receivers Make emergency services faster and more reliable As Global Postal Code to sort both domestic and international mail to final mailboxes automatically

24 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Business Cards The Universal Address can perfectly fit the limited space of a business card as part of an address to help people to reach the location more efficiently: Get direction and distance from street signs Pinpoint the location on maps Navigate to the location with GPS receivers Specify the location on location based services quickly NAC Geographic Products Inc. http://www.nacgeo.com Xinhang Shen, Ph.D. President & CEO 1608-45 Hintingdale Blvd.Tel: (416) 496 6110 Toronto, ON M1W 2N8Fax: (416) 496 9241 Canada NAC: 8CNB Q8Z4xshen@nacgeo.com Universal Address

25 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. GPS Watch Displaying Universal Addresses instead of geographic coordinates on a GPS watch can eliminate the need of maps and retain the real advantages of a watch: small, light, long battery life, low cost and easy to use. Widely using GPS watches will start a new era for using accurate spatial information just like accurate time. People will use Universal Addresses to record the accurate locations of accidents, crimes, discoveries, events, emergency needs, campsites, fishing spots, etc.

27 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. GPS Cellphone Manufacturers are shy to display geographic coordinates on a cellphone even if it has a GPS inside because they are useless to consumers. This will be changed by Universal Address because they are directly related to addresses, postal codes, street signs, maps, yellow pages, etc. Displaying Universal Addresses on cellphones will turn cellphones into powerful navigation tools.

28 International IT Conferences in Toronto on October 14-16, 2003 NAC Geographic Products Inc. Universal Map Grids Street maps use locally defined grids because accurate geographic grids based on UTM or longitude/latitude will produce long coordinates that are difficult for consumers to use. NAC Grids called Universal Map Grids has solved the problem. They can be applied on all kinds of maps and the grid coordinates are short Natural Area Codes. Universal Addresses can be directly pinpointed on all maps with NAC Grids. The location information on these maps are directly connected.
