UCLA Researchers are Using Geospatial Technologies to Identify Potential Ancient Buddhist Sites

Ad:

Archaeologists and geographers are looking at certain rock formations and other geographical anomalies to predict where the Buddhist king of northern India, Ashoka, left some of his ancient teachings.

Ashoka was the Buddhist king of the Mauryan Dynasty who ruled from 304 BC to 232 BC. Ashoka left transcriptions and proclamations, which researchers of Indian history and religion are greatly interested in. Researchers have located certain sites that are likely locations for some of these edicts, called predicting sites.

Using Predictive Modeling and GIS to Identify Potential Sites of Interest

Archaeologist Monica Smith and geographer Thomas Gillespie identified 121 locations that they hope will reveal some of Ashoka’s edicts using GIS analysis. The locations of 29 of Ashoka’s edicts have already been found scattered across India, Pakistan, and Afghanistan. The researchers took defining features of these 29 findings and researched other sites in ancient India that may also fit the characteristics of the original edicts.

Using predictive modelling the researchers were able to find over a hundred sites that might match the sites where Ashoka left his edicts. Global GIS datasets covering geology, population, climate and topography were used to develop spatial predictors.  The sites are incredibly important for religious reasons, but also for those who study the influence of this early political and religious movement. The history of Ashoka and his edicts will bring greater insight into the growth and creation of modern India, Pakistan, and Afghanistan. The sites have so far only been theorized in the research, but the predictive modelling may lead Indian and Pakistani scientists to more discoveries about this ancient king.

Predicting sites is only as good as the research that was conducted and the appropriate analyses that were conducted on the facts. Predictive modelling can be incredibly helpful in a wide variety of fields including meteorology, geography, volcanology, and now history and archaeology.
