Sub-surface geo / archaeological features using GPR data sets

With the Indus Valley civilization and several subsequent empires and kingdoms, India is one of the world’s archaeological gems. Be it ancient forts or some of the world’s oldest universities, India has more than a thousand known/ excavated archaeological sites over diverse geological provinces. Many of the sites with its extent are yet to be excavated and or mapped. Synergetic usage of Earth Observation (EO) satellite data and ground geophysical observation (Ground Penetrating Radar) has proven to be an effective tool for detection, delineation and mapping of shallow sub surface geo-archaeology and ancient cultural sites with its extent. Proposed study will help in building up scientific understanding and to correlate EO data and GPR signatures of geo-archeological features in known archeological sites (in fluvial Aeolian and coastal regions) to detect, delineate and map the extent of the buried cultural heritage sites.

Spectral library generation of rocks & archiving from various geological terrain in visible and thermal region

In this research domain, research is to be carried out to understand the role of mineralogy in shaping diagnostic absorption features imprinted on the reflectance/ emittance spectra of rocks and how mineral spectra of dominant to minor minerals contribute in shaping absorption, kinks in the mineral spectra. Research also should assess the role of linear or non-linear mixing arising due to textural change and how these hamper/influence the diagnostic absorption feature. Research attempt can also be made to prove/assess the utility of spectrometric parameters of absorption/emissivity features in estimating grade of the ore bearing samples.
