Geographic information is critical to promote economic development, improve our stewardship of natural resources, and protect the environment. Modern technology now permits improved acquisition, distribution, and utilization of geographic (or geospatial) data and mapping. The National Performance Review has recommended that the executive branch develop, in cooperation with State, local, and tribal governments, and the private sector, a coordinated National Spatial Data Infrastructure to support public and private sector applications of geospatial data in such areas as transportation, community development, agriculture, emergency response, environmental management, and information technology.”

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

The National Geographic Information Infrastructure is a collection of policy, data sets, standards, technology (hardware, software and electronic communications) and knowledge providing a user with the geographic information needed to carry out a task

La technologie, les normes ainsi que les systèmes et les protocoles d’accès nécessaires pour harmoniser toutes les bases de données géospatiales du Canada et les rendre accessibles dans Internet constituent l’Infrastructure canadienne de données géospatiales.

ANZLIC views land and geographic information as infrastructure, with the same rationale and characteristics as roads, communications and other infrastructure. As the peak co-ordinating body for the management of land and geographic information, ANZLIC believes that Australia and New Zealand should have the spatial data infrastructure needed to support their economic growth and their social and environmental interests, backed by national standards, guidelines, and policies on community access to that data.

The term “Spatial Data Infrastructure” (SDI) is often used to denote the relevant base collection of technologies, policies and institutional arrangements that facilitate the availability of and access to spatial data. The SDI provides a basis for spatial data discovery, evaluation, and application for users and providers within all levels of government, the commercial sector, the non-profit sector, academia and by citizens in general.
The word infrastructure is used to promote the concept of a reliable, supporting environment,
analogous to a road or telecommunications network, that, in this case, facilitates the access to geographically-related information using a minimum set of standard practices, protocols, and specifications. The applications that run “on” such an infrastructure are not specified in detail in this document. But, like roads and wires, an SDI facilitates the conveyance of virtually unlimited packages of geographic information.
