Universal geocoding question

June 24th, 2011 by Susan Smith

I read your article about Universal geocoding.

Universal
Geocoding NAC Assigns Unique Codes to Every Location on Earth

I was wondering how this would apply to a deeply populated area with homes duplexes and High-rises. As you understand it, would there be a geocode for each address or living space or would it be a general geocode for the city block or building? What ever additional information you might have would greatly be
appreciated.

Thank you
Ron

Usually, a Universal Address contains the information of the horizontal
location only. For a building, it’s the location of the entrance. However,
as we discussed on http://nacgeo.com/nacsite/documents/postal.asp, for
simplifying automatic mail sorting purpose, it allows residents of a
building to add a third string to represent the room number, such as

NAC: 8CRB Q90H UNIT208

so that the OCR software can sort the mail into the final mail box. The
locally defined third string must contain vowel character(s) (A, E, I, O, U
or Y) to distinguish it from a standard altitude string which does not have
any vowel.
