In response to the need to map hazardous sites that were inundated by the widespread Mississippi river floods of 1993, LandView became a separate CD-ROM product that was released in 1995 as LandView II. LandView II included additional EPA-regulated sites and recently released 1990 Census socioeconomic demographic data. 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.LandView IV was released to the public on DVD-ROM in November 2000. This version of LandView contained an revised LandView program interface that would run on 32-bit operating systems like Windows 98, NT, and 2000 and support faster processors. Use of DVD technology supplanted the 11 CD-ROM LandView III set with a single DVD. This enhancement allowed a user to view detailed road networks and other features anywhere in the nation without having to change discs. The new LandView software allowed users with Internet connections to connect to on-line databases of each agency to get the most up-to-date information for a particular map site. The greater capacity of the DVD allowed the popular population estimator used for calculation of population within a radius for such things as the EPA Risk Management Plans (RMP) to provide more accurate results based on 7 plus million 1990 census blocks. Because all the block data could be stored on the DVD in a single database, users could now able to do radius calculations crossing any combination of state boundaries. In addition, the additional disc capacity allowed for the expansion of the data from the USGS GNIS which additional information regarding places and features contained on USGS maps. LandView 5 was released in November, 2002 as a two DVD set (East/West DVDs). It contains updated EPA and USGS Geographic Names Information System (GNIS) data, selected Census 2000 SF1 data plus computerized street maps based on Census 2000 TIGER/Line. We are currently working on LandView 6 which will contain updated EPA and USGS data plus selected Census 2000 SF3 data (socioeconomic data).
