What’s special about GIS?
Geographic Information Systems (GIS) have emerged as a key technology to manipulate and analyze geographic data. Though there are many roots of GIS (and they are often intertwined).
The term GIS was first coined in the early 1960s by Roger Tomlinson during his work with the Canada Land Inventory (CLI). At that time, a system was needed to analyze the data collected by the CLI to support the development of land management plans for rural areas of Canada. In the United States, the Bureau of the Census developed the DIME-GBF data structure and street database in preparation for the 1970 census (in 1967), and the TIGER topological data structure in 1988. Howard Fisher established the Laboratory for Computer Graphics and Spatial Analysis at Harvard University in 1964, and work accomplished in the 1970s and early 1980s had a major influence on the development of GIS. A number of software packages were developed there: SYMAP, CALFORM, SYMVU, GRID, POLYVRT, and ODYSSEY. Jack Dangermond, a Harvard Lab graduate, founded Environmental Systems Research Institute (ESRI) in 1969. Many of the ideas used to develop ARC/INFO, first released in the early 1980s, originated from ODYSSEY.1
