In geography, many innovations in the application of information technologies began in the late 1950s, 1960s and early 1970s. Methods of sophisticated mathematical and statistical modeling were developed and the first remote sensing data became available. Researchers began also to envision the development of geographic information systems. The mid-1970s to early 1990s was a period of contagion. The first commercially available software for GIS became available in the late 1970s and spurred many experiments, as did the development of the first microcomputers in the early 1980s.
