Geographical Information

National Data Sharing

Further, with the availability of precision, high-resolution satellite images, data enabling by the organization of Geographical Information System (GIS), combined with the Global Positioning System (GPS), the accuracy and information content of these spatial datasets or maps is extremely high.

The Metadata standard specifies the elements needed to support the establishment of NSDI Metadata and also for major uses of metadata.Encapsulating these maps and images into a National Spatial Data Infrastructure (NSDI) has been recognized and the emphasis is on information transparency and sharing, with the recognition that spatial information is a national resource and citizens, society, private enterprise, and government have a right to access it, appropriately. Only through common conventions and technical agreements, standards, metadata definitions, network and access protocols will it be easily possible for the NSDI to come into existence.

Much of this information is spatial - i.e. it refers to a coordinate system and is representable in map form. Current and accurate spatial data must be readily available to contribute to local, state and national development and contribute to decision making, economic growth, environmental quality and stability, and social progress. Encapsulating these maps and images into a National Spatial Data Infrastructure (NSDI) has been recognized and the emphasis is on information transparency and sharing, with the recognition that spatial information is a national resource and citizens, society, private enterprise, and government have a right to access it, appropriately.
