GEOTECHNOLOGY AND SOCIETY It’s a
Mean Pinball Game Bruce Westcott
I confess: I’m anxious. The next-generation
Internet protocol will make it possible for every person
or device (in the world!) to have an Internet protocol
address. Maybe you or your organization can provide some
sort of Web-accessible geospatial service, you know that I
need, when hunger or disaster strikes. Now your updated
imagery service, sensor, or spatial widget can have its
own URI (Universal Resource Identifier)!
The Information Policy Subcommittee of the U.S.
House advises, “There are tens of thousands of entities
securing and utilizing an almost infinite amount of data
for their individual goals and missions—not to mention
emerging ‘new’ uses of geospatial data.”
I immediately envision a cyber-world in which
I’ll be even more confused than I am now when I try to
buy toothpaste at Wal-Mart. It will be a world in which
the numbers of aisles, with their shelves of toothpastes,
are endless. Viewed from another perspective, there will
be a tube sitting on some shelf out there just waiting to
ooze the right flavor for me, and its marketing maven will
be anxious that I know precisely where it is. How will I
find what I want? I envision a giant electronic game of
chance.
Behold: Google, Yahoo, and others will fight to
give me personalized search results, and tell the
toothpaste folks just how to tag their toothpaste URI so
that my search will turn it up. Right? Not so fast.
Isn’t all the hardware needed to “wire” the
world falling into place? It’s cheaper, faster, and more
reliable, too. Implementation of crucial protocols and
standards is inevitable and moving fast (Figure 1);
examples include the new protocol for URIs,
interoperability specifications from the Open GIS
Consortium (OGC), and others.
All of this will give us an infinite pick list of
spatial data and services at our fingertips, potentially
enabling us to perform complex spatial operations with the
best available data 24/365, right? What’s more, most of
the required infrastructure and resources are brought to
us at a marginal cost that is negligible or transparent.
The potential payoff has already motivated the providers
of data, services, and infrastructure to make the required
investments.
This is a cyber world which offers incredible value
to all of us. Or does it?
Rather, isn’t it really a world in which we have
to hedge our bets on using most of these resources, those
that we don’t know enough to trust? Aren’t we actually
oblivious to who is putting what content out there, and to
their motives and competencies? How am I to know whether
the most timely pricing/availability/location information
for my toothpaste is available at www.walmartdeals.com or
at www.deepdiscountstuff.net?
My concern is that the value potential for
Web-based geospatial data and services (and toothpaste as
well) is compromised by a gap in the chain from producer
to consumer. The gap is called “quality.” This term
encompasses many concepts: timeliness, truthfulness,
completeness, integrity, appropriateness, and more. High
quality geospatial data and services surely are abundant,
but there is no systematic, reliable way for producers to
describe their quality using the same terms and
technology. And consumers must be able to easily access
“quality” information in order to judge the relative
value of competing toothpastes on that seemingly endless
numbers of shelves and aisles. For example:
-
United States Department of
Agriculture (USDA) nutrition labels accomplish the basic
purpose for consumables, but you wouldn’t depend on them
if there were a chance of plutonium in your peanut butter.
The value (risk) of going nuclear for lunch simply
requires information of higher quality or greater depth.
But you believe the USDA is trustworthy and you know how
to contact them. That knowledge conveys integrity, which
itself has value.
-
Standardized geospatial metadata
often provides some information about candidate data sets
for your geospatial application, but the most valuable
information it conveys is usually the contact information.
This allows you to ask follow-up questions about the
“who, why, when, what?” that assure the quality you
require. But how do you feel about a dataset you can
download from ftp.phaedrus. org that has skeletal metadata
and no useful contact information? This doesn’t sound as
warm and fuzzy as USDA, does it?
Don’t we need to invest in better technology and
in the “quality” information required to support
high-value decision making in cyberspace? Otherwise, the
Web is really just a big pinball machine, and we’re all
“deaf, dumb, and blind” kids out there hoping for some
luck. But you already know the lyrics and the rest of the
story.
