Computerized GIS did not come from one company or one product. It grew from a rich stew of government land inventories, university mapping software, CAD workstations, utility databases, and professional planning organizations. Roger Tomlinson’s CGIS gave the field its foundation. Harvard’s SYMAP software proved computer mapping could scale. Intergraph, Synercom, Comarc, and ESRI began to commercialize GIS software in the early 1980s. Hardware companies like Tektronix, Calcomp, Summagraphics, and Versatec supplied specialized equipment. Their combined work turned maps into spatial databases and, eventually, into today’s location-aware analytics platforms for cities, infrastructure, logistics, climate, and AI systems.
