Summary
What is SDI?

SDI = Spatial Data Infrastructure

What is Spatial Data?

What is an Infrastructure?
Definition (Oxford dictionary)

“The basic systems and services
that are necessary for a country or
organization”
Infrastructure

Infrastructure facilitates the production of
goods and services
Characteristics of an Infrastructure
Time Span
Long-term activity (10-100 yrs)
Users
Large users groups
Funding
Tax money or obligatory amount per
user
Management/
Control
Government, monopolist, political
debate

Definitions of SDI

Executive Order of US (1994) National Spatial
Data Infrastructure (NSDI) means the technology,
policies, standards and human resources
necessary to acquire, process, store, distribute,
and improve utilization of geospatial data.
Definitions of SDI

Wytzisk and Sliwinski (2004) A SDI can be
understood as a multi-leveled, scalable, and
adaptable collection of technical and human
services, which are interconnected across
system, organizational and administrative
boundaries via standardized interfaces. Those
services enable users from different application
domains to participate in value chains by gaining
seamless access to spatial information and geoprocessing resources.
Definitions of SDI

Utility view: SDI is a network facility for accessing
and sharing spatial data.

Component view: spatial data, standards, policies,
technology and people

Utility and goal: a network facility for supporting
spatial issues in society accessing and sharing
spatial data
Characteristics SDI

Holistic concept
Complex system (see Paper Grus et al. in Reader)
Serving the organization/society not only a
particular application
5 components and interaction between
components
