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 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

Summary

SDI: infrastructure for Spatial data 5 Components World-wide development (also RS data) Long term activity Difficult to organize

Final Remark

We (Lukasz, Vicky and Arnold wish you a good 2015 and fruitful SDI course!
