Folie 11 Definition in legal document of the US Federal Government (1994) SDI as a minimum infrastructure, includes applications, standards, technology and institutional governance necessary for effective and efficient spatial data and services management within or across organizations. SDI on different levels (e.g. Europe: INSPIRE, National: GDI-DE) The concept of National SDI (SDNI) is now being universally called the Spatial Enablement of Governments and Societies (UN Declaration from Kuala Lumpur, 2011) Slide 11 Spatial Data Infrastructure Source:

Folie 12 Spatial data set spatial data, framework spatial data and meta-data Standards Standard of spatial data contents, Standard of data exchange, Standard of meta-data and Standard of data services Access to data Data Discovery, Data Access and Data Process Technology Hardware and Software Equipment, Data Communication Network Policy - Legislation Mechanism, Policy and Legislation regulated by the State Organization Institution including Organizations Arrangement and Relationship between Organizations Partnership Investment Funding, Human Resources Development, Public Awareness Raising, Scientific Research and International Cooperation) Slide 12 Vietnam NSDI (VNSDI) Source:

Folie 13 Slide 13 Potential for a SDI Pros availability support of Standards Service Orientated Infrastructure adoptable for other regions easy to transfer to other server due to Virtualization platform for further development Cons no synch between instances of the system performance must be tested for larger scale application
