Infrastructure projects are being implemented since beginning
of humans civilisations started building infrastructure. Spatial
data collection, its integration and management also has a
long history.
Despite the long history of the usage of geospatial technologies
though survey, photogrammetry, CADD and GIS, exploitation of
these technologies to continuously service entire infrastructure
lifecycle is rarely, if ever, accomplished to available potential.
These shortcomings are largely attributable to the historic and
arbitrary segmentation of the geospatial world. Surveyors, engineers,
geographers and facility operators come from differing
backgrounds perspectives and purposes. As each is professionally
driven to focus on their segment of the infrastructure lifecycle,
none are readily able to see the “big picture” opportunity to
integrate across segments and build a spatial value chain.
The geospatial marketplace is poised to unlock this unexploited
value with the emergence of three primary dynamics: 1) open
standards; 2) three dimensional (3-D) viewers; 3) development of
geospatial technology at the consumer level. Open, published
standards have created a truly interoperable environment in
the geospatial industry. XML-based file formats (GML, KML,
GeoRSS) and exchange frameworks (FDO) are the foundation for
this interoperability. The incorporation of these open standards
into commercial products means that the same geospatial data
can be read natively by virtually any geospatial technology, be
it a GPS data collector, CADD software or GIS web server. Heretofore,
3-D technology has been relegated to niche design tasks
and small scale visualization. The current 3-D geospatial phenomenon,
driven by the deep pockets of the likes of Google and
Microsoft, has thrust this rich visual and geospatial context
upon the masses. This, in turn, is driving traditional and new 3-
D geospatial applications such as building information modeling
(BIM). Concurrent with the introduction of 3-D geospatial to
a wide audience is the presentation of consumer interest data
on a map using national and global scope datasets including
transportation systems, political boundaries and address
geocoding. All of these things have led to a new “pull” for
geospatial information where it previously did not exist. Consumers
want access to information about their world (including
the physical infrastructure) in real-time 3-D through their web
browser. Citizens and customers have spoken, how does the
infrastructure world respond?
Where and in what condition is the data? Governments and
businesses have invested for years in spatial databases and
solutions to operate aspects of their operations (segments of the
infrastructure lifecycle) more effectively. Tremendous amounts
of spatial data are locked away in proprietary formats and systems
making it difficult and costly to distribute. Most organizations
maintain data in different formats and storage locations.
Locating and distributing this data is a tedious process relying
on extensive extract, transform and load procedures. This same
data frequently requires spatial operations, classification or rendering
as part of the ETL process. Providing the appropriate data
in the correct form to the end user requires a holistic approach
to geospatial systems development. It also requires an approach
that leverages legacy systems without costly refactoring and
migration. In the short term, existing data stores must be
accessed via ETL and loosely coupled web service interfaces.
For the future, the entire spatial data lifecycle must be optimized
and each contributing process improved so that all
relevant infrastructure data
are efficiently and effectively
produced, managed
and served from planning
through construction and
on to operation. (see Figure)
How and where will the
end users interact? As the
use of geospatial technology
expands, the proportion of users who edit and update spatial
geometry and attributes is going down.
Most users are interested
in basic spatial queries (e.g. location and proximity) or reading
spatial context into other business data. This allows for, and
in fact requires, that primary access to geospatial data be provided
through light-weight client and web-based integration
platforms. When 90 percent of end users do not require access
to the powerful geoprocessing capabilities of a full blown GIS,
the consumer-level interfaces become the mainstay. With their
support for open GIS and web standards, the ability to leverage
legacy geospatial and business data is simple and tremendously
cost-effective.

The confluence of these three dynamics - open standards, 3-D
technologies, and consumer adoption - will bring us closer to
achieving the potential of a spatial value chain across the infrastructure
lifecycle. It is expected that this will at long last result
in geospatial information serving and being enhanced by each
segment in the lifecycle from conception to operation.
