NSGIC views on National Addressing

Most
GIS'ers have used address data, at one time or another, for geocoding or
routing purposes.  Whenever possible we use the best information available
which, for addressing, always comes from the local jurisdiction(s).  For
various reasons (e.g. project size or lack of a local locator file) we
sometimes also need to use some other collection of addresses - knowing that
these are more flawed and not based on the best, most current, information.

Wouldn't it be nice to
have a cross-jurisdictional, cross-state, and fully national address file built
from the expert work of local custodians?  Of course there are many
challenges in getting there.  NSGIC has penned a letter to the National
Emergency Number Association (NENA) explaining how those challenges should be
prevented at the national and Federal levels.  The text of that letter is
linked to this article (as .PDF).

Within Arizona, many of
you have been contributing to AGIC efforts, with our state 9-1-1 Program Office
and the State Cartographer's Office, to aggregate local addresses into a
unified statewide data model for emergency response needs.  This work has
obvious benefits.   Our state model, though still a work in
progress, is very highly regarded and is being examined by other states and the
USDOT as a likely methodology for building a National Address Database (NAD).
  In concept the NAD is a build once, use everywhere concept.  In
this model, the states would assemble addressing for internal business purposes
(e.g. emergency response, allocations, revenue, etc.) and then deliver a small
subset (address/sub-address only) to the NAD aggregation. 

The newest challenge, at
the national level, is the news of a National Emergency Address Database (NEAD)
being developed in a proprietary, non-shareable fashion, in a partnership with
organizations controlling cellular communications. No one argues that cellular
information is not extremely valuable to emergency dispatch.  The problem
NSGIC sees with the NEAD work is that their data may be unique and
not-shareable.  NSGIC believes that the NAD process should inform a NEAD
and, in return, a NEAD including cellular hot spots could inform a NAD.
