Evolution of Geographical Information Systems

SUMMARY Geoinformatics is described as a scientific and technical complex integrating the branch of scientific knowledge, the appropriate technology and the applied, or productive, activities concerned with the development and implementation of geographical information systems. Four stages of geoinformatics evolution are discussed, and its prospects are outlined in brief. 1. Introduction Geoinf...
