Introduction
National Spatial Data Infrastructure encompasses the policies, standards and institutional arrangements involved in delivering spatially-related information from many different sources to the widest possible group of potential users.

Spatial Data infrastructures - Introduction

The development of national infrastructures for geographic (spatial) data has received considerable attention by government data producers, the private sector, academic organizations, and the user community in various countries in the Americas, Europe, Asia, and Africa. The term NSDI originally referred to the first national efforts for data exchange between official national entities that produce geographical information. Currently, the term NDSI encompasses the producers, systems, connections to Internet, standards, and institutional elements involved in the development and delivery of geographic or georeferenced information generated by various organizations to satisfy the needs of the widest group of potential users.
These infrastructure components are being implemented in different forms and at different speeds worldwide depending on the circumstances in each nation. The particular data mixture, access mechanisms, tools, laws, policies and institutions and the needs derived from the environmental and socioeconomic conditions of each country determine the national requirements for spatial information, the characteristics of the market, and ultimately, the concept and priorities of each NDSI.
Technological advances and the efforts of the most developed countries are playing an important role in changing traditional approaches for acquisition, organization, distribution and diffusion of geographic information at domestic and transnational levels. These changes have been occurring intensely since 1996, when an initiative for the development of a global spatial data infrastructure (GSDI) came into being. This global initiative depends upon the interconnection and harmonization of all national infrastructures (NDSI'S). In conjunction with the global effort, regional spatial data infrastructure initiatives have also be formulating in Europe, Asia/Pacific, Africa and, recently, in the Americas.
