THE NEED FOR A NATIONAL SPATIAL DATA INFRASTRUCTURE. IN: THE GEOGRAPHICAL DIMENSIONS OF TERRORISM
Since about 1980, collection of digital spatial data has grown beyond the few early adopters to include virtually all resource management, facility management, and governing organizations in the U.S. This data was collected in raster imagery form as well as detailed vector databases to support general mapping, facility management, resource management, visualization, and spatial analysis. Raster data is represented by pixels, while vector data represents features as points, lines, and polygons. These data types exist at various scales from small scales with national and infrequent coverage and low accuracy, to large scales with local, intermittent coverage and higher accuracy. The prime motivations for collection and maintenance of these data sets are to provide more efficient management of facilities and resources, more effective analysis of geospatial relationships, and to simplify the mapping of data. While a wide range of spatial data exists, how these spatial data resources are collected and how they can be marshalled to support anti-terrorism and crisis response activities are key concerns and the focus of this paper.
