Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
The FGDC coordinates the sharing of geographic data, maps, and online services through an online portal, geodata.gov, that searches metadata held within the NSDI Clearinghouse Network. [5] Spatial Data is considered a national capital asset.
Unlike the NSDI Clearinghouse Network, GOS was built around a centralized metadata catalog database, with an architecture that links users to data providers through a Web-based geoportal. The user of GOS may employ a simple Web browser (thin client) or may interface directly with a GIS (thick client).
GIS data acquisition includes several methods for gathering spatial data into a GIS database, which can be grouped into three categories: primary data capture, the direct measurement phenomena in the field (e.g., remote sensing, the global positioning system); secondary data capture, the extraction of information from existing sources that are ...
The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas for the United States and Puerto Rico. [2] These statistical areas are important geographic delineations of population clusters used by the OMB, the United States Census Bureau, planning organizations, and federal, state, and local government entities.
In late 1984, ITC was awarded a grant from the Dutch Ministry of Foreign Affairs, which led to developing a geographic information system (GIS) which could be used as a tool for land use planning and watershed management studies. By the end of 1988, a DOS version 1.0 of the Integrated Land and Water Information System (ILWIS) was released. Two ...

A spatial data infrastructure (SDI), also called geospatial data infrastructure, [1] is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way.
