Building European spatial data infrastructures.
Building European spatial data infrastructures A Spatial Data Infrastructure or SDI is a framework of spatial data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. .

The full potential of geographic information systems geographic information system (GIS)
Computerized system that relates and displays data collected from a geographic entity in the form of a map. The ability of GIS to overlay existing data with new information and display it in colour on a computer screen is used primarily to will not be realized until governments maximize access to geographic information through spatial data infrastructures, according to according to

Analytical techniques to determine the spatial distribution of a variable, the relationship between the spatial distribution of variables, and the association of the variables of an area. , U. College London, UK), who examines the institutional and decision-making tasks involved in their development and implementation by public-private partnerships. He describes the range of GIS applications available, introduces the concept of spatial data infrastructures (which "includes the materials, technology, and people necessary to acquire, process, and distribute [geographic] information to meet a wide variety of needs"), describes the current state of spatial data infrastructure in Europe, explores the need for an integrated infrastructure strategy at the European level, considers the legal framework for the INSPIRE (Infrastructure for Spatial Information in Europe) initiative, and identifies key strategic issues for future development of spatial data infrastructures.
