LandView IV is a CD-ROM based "Federal Geographic Data Viewer" that provides database extracts from the Environmental Protection Agency (EPA), the U.S. Census Bureau, and the United States Geological Survey (USGS). These databases are presented in a geographic context on maps that contain jurisdictional entities (states, counties, cities & towns, congressional districts, and others), detailed network of roads, rivers, and railroads, census block group and tract polygons, schools, hospitals, churches, cemeteries, airports, zip codes and other landmark features.
The LandView system consists of two software programs: the LandView database system and the MARPLOT® mapping system. These two systems communicate with each other to allow you to make map inquiries based on a selection of database records, and to make database inquiries based on a selection of map objects.
History of LandView
LandView has its roots in the CAMEO system (Computer-Aided Management of Emergency Operations). CAMEO was developed by the Environmental Protection Agency and the National Oceanic and Atmospheric Administration to facilitate the implementation of the Emergency Planning and Community Right-to-Know Act. This far-reaching law requires communities to develop emergency response plans addressing chemical hazards and to make available to the public information on chemical hazards in the community.
CAMEO DOS, first released in 1991, contained a mapping program called MARPLOT, which provided access to computerized street maps based on the U.S. Census Bureau TIGER/Line® files. MARPLOT was subsequently enhanced to include Census boundaries and demographic statistics, and was included in the TIGER/Line 1992 CD-ROM product, under the name of LandView.
With the addition of EPA-regulated sites and more detailed demographic data, LandView became a CD-ROM product in itself, released in 1995 as LandView II. Being a DOS-based program, LandView II was limited by the DOS memory restrictions, and was difficult to run in memory-intensive environments, such as local-area networks. To solve that problem, and to provide additional capabilities and ease of use, the LandView software was converted to the Windows platform. Two programs were developed, MARPLOT for Windows (the mapping engine), and LandView (the database search and query engine). Both programs have also been converted to run on the Macintosh platform. This Windows/Macintosh cross-platform system, with the inclusion of updated Census and EPA data, and data from several other federal agencies was released on CD-ROM as LandView III in January 1998.
