A small Canadian company is seeking support to standardize
a new address system that would work with maps, geographic
databases and GPS systems to make life easier for everyone
from travellers to postal workers.
"We originally developed this because we thought there was
a need for some sort of international postal code - every
country has a different system and it's confusing," Xinhang
Shen, president of Toronto-based software developer NAC
Geographic Products Inc., told globetechnology.com. "Simply
using longitude and latitude would be too long for people to
remember, or even to fit on an envelope, so we developed an
algorithm to optimize the representation of a geographical
location and make it more compact."
The Natural Area Coding system Mr. Shen's company developed
can represent an area the size of a province using two
alphanumeric characters. A "universal address" with six
characters takes things down to a box measuring 1 kilometer
per side, and boosting it to 10 characters represents a
specific area measuring one square meter.
"With NAC, everything is efficient," Mr. Shen said. "For
example, four characters would represent a city like Toronto,
whereas it would take more than 20 characters with current GIS
systems."
Mr. Shen's company proposes a 10-digit universal address
for homes and businesses. It would be slightly longer than
Canada's six-digit alphanumeric postal code, but it would be a
standardized system that would work around the world. For
example, NAC Geographic Products' address in Toronto would be
8CNB5 Q8Z4R.
"The Holy Grail in terms of addresses is a simple system
that will work in all countries," said Tim Evangelatos,
Strategic Technologies and Policy Advisor for GeoConnections
at Natural Resources Canada in Ottawa. "The idea is not unique
by any means, but this system is interesting and it builds on
other things that have been proposed for more than a
decade."
The NAC system can make mail delivery more precise and
efficient, Mr. Shen said, but it is also useful for geography
specialists trying to locate maps of specific areas. Natural
area codes could be used for search and rescue, by
municipalities trying to inventory things like traffic lights
and fire hydrants, and by people simply trying to get from
point A to point B.
Natural area codes can be plugged into electronic map
software and global positing systems (GPSs) that have been
configured to recognize them, but people can also use NACs to
find locations on simple paper maps that are organized using
his company's system, Mr. Shen said.
By adding characters, NACs can also represent a point in,
around or above the earth, using the centre of the earth as a
reference point. This is handy for poinpointing areas
underground for mining companies, or in space for satellites,
Mr. Shen said.
As Mr. Evangelatos pointed out, the concept of a universal
area code is not new - many public and proprietary ideas for
such a system have been proposed in recent years.
"But this is an elegant solution that seems to supply
something that is becoming necessary as the world becomes more
globalized - it certainly solves a lot of the problems with
current systems," said Matt Ball, editor of Boulder,
Colo.-based GeoWorld magazine and show manager for the recent
GEOTec conference in Toronto.
"It's a relatively simple system that does much more than
an existing [postal] code. It goes to a position based on
longitude and latitude without the complexity of listing the
longitude and latitude, and it's more streamlined and
accurate," he said.
But even though the system looks promising, it's extremely
difficult to get the attention of international standards
organizations, Mr. Ball added.
"Implementing something like this is hugely challenging,
because you have to deal with multiple countries, governments,
jurisdictions, and so on," he said. "I see just the political
obstacles to implementation being fairly huge. It's something
that's needed, but it's similar to trying to enact the Metric
system in terms of promoting adoption."
As a result, Mr. Shen said that while he is pitching his
natural area code system to a number of world standards
groups, he is also seeking corporate partners to help push the
system in the private sector.
Still, whether he goes the public or private route, the
journey likely won't be easy for NAC, critics say.
"It's really, really hard to make something a standard -
old traditions die hard, and there are so many official bodies
involved," Mr. Evangelatos said. "But I did find the idea
interesting, and if he can sell the idea to people who have
money and resources, you never know, it could eventually
become the basis of a de facto standard."
He added that while it's too hard to say whether NAC will
succeed in becoming a standard, "at the very least, this will
be a spark for debate and discussion, which could lead to
better things."
Mr. Ball, too, is unsure whether NAC will be successful in
its drive to standardize its natural area code system, but he
said it's a concept whose "time is just around the
corner."
"It's only a matter of time before something like this will
be implemented. This particular system may be a bit ahead of
its time, it's hard to speculate, but so many advancements in
geospatial technology are really creating a digital world,"
Mr. Ball said. "This is a vision a lot of people have, because
it breaks down barriers to interoperability of data with a
standard reference system, and that would be a huge benefit
for everyone."
