According to this article in the Toronto _Globe & Mail_, a Canadian company, NAC (stands for Natural Area Code) Geographic Products, is pushing for a standardized worldwide address system that would work with maps, geographic databases, and GPS systems.
2 alaphanumeric characters would represent an area the size of a province. 6 characters, an area 1 kilometer square. 10 characters, a square meter.
NAC proposes a 10-digit universal address for homes and businesses. For example, their Toronto address would be 8CNB5 Q8Z4R. The address would take up fewer characters than the latitude and longitude. Additional characters could indicate elevation above or below the ground.
The main barriers to universal adoption of this system are political--so many countries, states, provinces, cities, etc. But suppose it did catch on, Hank could get the database at a reasonable price, and it was possible to for a Georger to know the NAC of his/her location at any give time.
Then we'd really be able to see where George has been and track where he goes next!
