About us

I joined Department of Civil Engineering, IIT Guwahati in June 2015. Since then, I have been teaching and research in different areas of Geomatics and Earth Science. In summer semester (Jul-Dec), I offer "Precision Remote Sensing", which is a Post Graduate course and covers precision remote sensing technologies, namely GPS, LiDAR, Photogrammetry, and Bathemetry. In winter semester (Jan-May), I offer two Under Graduate courses, namely, "Surveying" and "Surveying Laboratory". My major research areas are airborne data acquisition and terrestrial data acquisition for 3D mapping. In addition, for any geospatial project or application, I provide solutions in many dimensions including 'understanding requirements of the project', conceptualization of data acquistion', 'generation of appropriate specifications', 'methodology development for execution strategy in field for data acquisition', and 'proof of the concepts'.

For airborne projects, I provide flight planning solutions for airborne data acquisition. Specially, if a project uses new sensors and aerial vehicles (like UAV) with new project requirements, I provide solutions for the conceptualization of data acquisition process, proof of the concept, and execution strategy in field for data acquisition. Similarly, for terrestrial data acquisition work, I derive various strategies of data acquisition with minimum time for a specific geospatial application.
