The survey, a first-of its kind, was undertaken by the varsity in collaboration with the Research Institute for Humanity and Nature (RIHN), Kyoto (Japan) to clear doubts over the geographical accuracy of such endangered heritage sites, which were first discovered during the 1920s and 30s, Principal Investigator, Gujarat Harappan Sites Gazetteer Project (GHSGP) and Professor at Department of Archaeology and Ancient History at MSU, Ajitprasad, said.
Subsequently, in June 2010, a research programme for creating a Gazetteer of Harappan sites in Gujarat was undertaken jointly by the institutes, he said.
"The primary aim of the research programme was to correct the geo-coordinates of over 700 Harappan and affiliated sites reported over the years by several scholars and researchers in Gujarat," he said.
Also, this survey was necessary to make the data useful for modern Geographical Information System (GIS)-based research and analysis, he said.
