Since the early 1990s, GIS, or geographic information systems, has been a crucial tool in archaeology. Indeed, GIS and GIScience, or Geographic Information Science, were utilized, developed, and adopted early on by archaeologists. Since archaeology frequently includes the study of the spatial dimension of human activity across time and all archaeology carries a spatial component, the combination of GIS and archaeology has been thought to be a natural match.
The outcomes of archaeological research are rich in spatial information because archaeology examines the progression of historical events across geography, time, and culture. GIS is skilled at processing these massive amounts of data, especially georeferenced data. It is a quick, accurate, and affordable instrument.
