How GIS is Used to Understand History

Ad:

Historical events are increasingly understood within geospatial contexts, where key events, circumstances, and reasons as to why given outcomes occurred are interpreted using GIS. As an example, historical geography is one area that has applied GIS to understand outcomes of battles, why cities were built in given locations, and using ancient technologies to understand length and difficulty of travel at different times of the year.[1]

Visualizing History Using GIS

These examples demonstrate how GIS has transformed the field of history so that our understanding of historical events is better contextualized. One recent example includes studying Roman harbors in the Mediterranean Sea.[2] Here, we know trade was vital to the Roman Empire; however, journeys across parts of the Mediterranean would have been difficult during certain times of the year, as winds and other factors vary. Therefore, GIS could be used as a forecasting tool to determine likely routes of shipping lanes in the past, where discovered shipwrecks and amphora, or cargo carried by ancient ships, are used to validate these route estimates.

Teaching History Using GIS

Teaching history now is made easier by visualizing to classrooms and students places mentioned and GIS analysis could be used to provide students with historical awareness, such as how far armies traveled and the types of terrain they encountered.[3] One area where GIS has been more recently used in understanding the past has been reconstructing ancient sites or places so that one can visualize in 3D and understand how individuals experience cityscapes or landscapes in the past as they walked through them. This includes understanding Maya architecture and landscapes.[4] This particular project used Web3D GIS and a customized tool called QueryArch3D. For historians, these tools offer a unique way to understand the past by reconstructing it using available historical or archaeological data.
