Applications of satellite remote sensing for research and heritage management in Indian prehistory

Abstract: Multidisciplinary spatial studies are relatively limited in Indian archaeology, despite their potential for research and heritage management. This paper discusses applications of satellite remote sensing, field studies and GIS, in the context of Palaeolithic archaeology. The study region covers an area of around 8000 km2, in the state of Tamil Nadu, South India, and is characterized by a rich and diverse Palaeolithic record. Satellite images of varied spatial resolutions were interpreted to address both regional and site-specific research questions. Thematic maps were generated from satellite data and refined with intensive field investigations. These were used for demarcating sources of raw material, and in investigating variability in the distribution of sites through time in relation to a range of geological and geomorphological features. Satellite data and field studies also aided in mapping impacts on sites resulting from modern landuse patterns. The paper also discusses the development and testing of a model to detect potential areas where new sites may be rapidly located. [Copyright &y& Elsevier]
