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 geo-processing 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

A short history of SDI
1991 Term SDI from Canada
1994 Clinton Executive Order 12906 (SDI)
1996 GSDI organization
2007 INSPIRE directive
1998 SDI course in Wageningen
Question
What are the difference/similarities between GIS and SDI?
Research themes
Summary
SDI: infrastructure for Spatial data
5 Components
World-wide development (also RS data)
Long term activity
Difficult to organize
Final Remark
We (Lukasz, Pinelopi and Arnold wish you a good 2016 and fruitful SDI course!
