No one asks for absolute accuracy. Although we note that in the mainland US
the accuracy seems to be fairly good most of the time. The island is a
large one and finding streets without functional software is difficult. Just
finding the zip code or the street would be a good beginning.
From what I see wandering around (looking for major streets, zip codes and
highways the software "Find" command can't) the address system, is similar.
If they can collect address data for my little home county in VA, which has
only 13,000 people. then they can collect it for PR too. Besides your
numbers are illusory. 4 M pop is correct, but add in an almost equal number
of transients (tourists, etc.). We can probably assume the FIND won't work
in Guam either as no Territories are named in the FIND list of states.
Microsoft's claim of "includes Puerto Rico and Guam" therefore becomes a half
truth as only half the mainland software functionality is present for the off
shore Territories (DC, on the mainland, works fine).
As proof of concept, note that tripquest.com seems to have no problem
locating the addresses, streets, or zip codes. Too bad they don't (yet)
offer a PR data download for import. Does anyone here have a source for the
location data so it can be imported?
Post by gpsmanAddresses are not usually located absolutely by consumer Desktop GIS
applications. See http://en.wikipedia.org/wiki/Geocoding
PR may have an entirely different method of addressing their streets
incompatible with the geocoding as performed by S&T.
And/or you have to consider the "usefulness" (profit potential), as
seen by Navteq, http://www.navteq.com/ of collecting address data for a
small percentage of a population of 4M occupying an area "slightly less
than three times the size of Rhode Island" according to the CIA.
