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
Why SDI? (Question 1) • What are the main reasons to initiate SDI development?
Views on SDI • Component view • CAS view (complex adaptive system) • Technological view • Organizational view • ???? • ????

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
Summary • SDI: infrastructure for Spatial data • 5 Components • World-wide development (also RS data) • Long term activity • Difficult to organize
Final Remark • We (Lukasz, Victor and Arnold wish you a good 2013and fruitful SDI course! • Questions?
