General

"A GDI is a system of (policy) measures, institutional facilities, technologies, data, and people that enable the sharing and efficient use of geographic information."

• The goal of a geospatial data infrastructure (GDI) is to provide users with direct access to geospatial information and geospatial services from multiple providers.
• GDIs exist at a wide variety of levels. Countries, municipalities, cities, etc. can build GDIs. At the European level, we find INSPIRE as the spatial data infrastructure of the EU.
• Users are the administrative bodies at all levels, professionals from the field of surveying, planning, construction, environment and the public

80 percent of all political and economic decisions have a spatial reference.
