Universal Geocoding from NAC Assigns Unique Codes to Every Location on Earth

GISWeekly: Who are some of your customers so far?
Dr. Shen: Our clients are the Government of Mongolia, the Government of Somaliland, hundreds of subscribers of our NAC Real-Time Geo-Services Suite and other companies under individual licensing agreements.

GISWeekly: How do you propose this is used in remote or forest areas where there is not very good coverage for smartphones?
Dr. Shen:
NAC itself does not need wireless networks. All smartphones with internal GPS should be able to get the NAC of their current location in remote and forest areas, just the same as to get lat long. If you want to use a GPS application which needs map data, then you’d better make sure that the GPS application is able to download and store the necessary map data in your phone. Once you have the map data, the GPS application should be able to work without network coverage.

According to a new research report by Berg Insight, the number of mobile money subscribers in emerging markets is forecasted to grow from 133 million users in 2010 at a compound annual growth rate (CAGR) of 40 percent to reach 709 million users in 2015. The total value of mobile money transactions will simultaneously grow at a CAGR of 54 percent from US$ 25 billion in 2010 to US$ 215 billion in 2015. Asia-Pacific is expected to become the most important regional market, accounting for more than half of the total user base.

CoreLogic released its April Home Price Index (HPI) which shows that home prices in the U.S. increased on a month-to-month basis by 0.7 percent between March and April, 2011, the first such increase since the home-buyer tax credit expired in mid-2010. However, national home prices, including distressed sales declined by 7.5 percent in April 2011 compared to April 2010 after declining by 6.8 percent* in March 2011 compared to March 2010. Excluding distressed sales, year-over-year prices declined by 0.5 percent in April 2011 compared to April 2010 and by 1.6* percent in March 2011 compared to March 2010.  Distressed sales include short sales and real estate owned (REO) transactions.

Combining remote sensing measurement tools with 60-meter meteorological tower data is an accurate, cost-effective alternative to collecting wind information vs. with 80-meter met towers alone, according to a cost analysis from Second Wind.

The analysis determined that one wind study using Second Wind's Triton remote sensing system and one 60-meter meteorological tower costs 35 percent less than the same study using an 80-meter met tower. Because of the portability of Second Wind's remote sensing system, the savings mount to 45 percent if two wind studies are conducted.

MAPPS, the national association of private sector geospatial firms, praised the adoption of an amendment in the U.S. House of Representatives this week that placed a moratorium on insourcing of commercial activities in the Department of Defense.

    While NAC is an interesting concept, it is at heart still a mostly proprietary system. Geoaddressing is not a new concept - the military (NATO forces in particular) have used the Military Grid Reference System for such purposes for decades. MGRS and its civilian counterpart, the US National Grid provide a unique advantage over NAC as they permit both point and area referencing based on context sensitive use and permit variable precision and accurary. By way of example a water valve located at a street intersection would be coded as a 10-digit number under normal use circumstances, an apartment would require 8 digits, and something large - say a football stadium - one could make due with either a 4 or 8 digit number. Before I get flamed on this - yes we understand that UTM zone junctions are not nice neat boxes. However, for map users this is not a problem - how a coordinate/geoaddress is read and used is consistently applied. For more information about the US National Grid/MGRS (the difference between the 2 is the datum NAD 83 for USNG, WGS 84 for MGRS - not of significance until sub-meter measurement is required), please visit:
    http://www.fgdc.gov/usng <-- note that this is a US standard - the ONLY coordinate system for which such a standard exists.

    When you do the math and look at what a 4 level, 30x30 grid ends up resolving to, it is an area of the earth approximately 49 meters square at the equator. Where I grew up, in a medium density American neighborhood, that would take in 4 separate residences. In a more densly populated area, even more. PLus this scheme does nothing to resolve the vertical component of an address for multi-story buildings.
    Nice add for Dr. Shens business though.
