Nanyang doctoral candidate talks on GIS applications

Staff Reporter

TIRUCHI: Earth's resources must be preserved for future in the interests of future generations, Queen Suraajini, a doctoral candidate of Nanyang Technological University, Singapore, emphasised while delivering a guest lecture on ‘Remote Sensing and GIS in Climate Change' at a programme organised earlier this week by the Institution of Engineers, Tiruchi Chapter.

Holding the distinction of being the first woman candidate from the Geo Informatics Department of Anna University, Chennai, to gain admission to direct doctoral programme of National Technological University, Singapore, M.s Suraajini explained that the GIS (Geographical Information System) applications cover agriculture, water, forestry, fisheries, ecosystem change, human health, identification of vegetation location, analysis of transportation routes, telecommunication sector urban planning, insurance, marketing and retailing, climate change and settlements. Ms.Suraajini was admitted to the doctoral programme that entails a monthly stipend of Rs.70,000 and tuition fee exemption of Rs.5,00,000 based on her GRE and TOEFL scores, and contribution to GIS through research and project papers.

She explained further: “Geo Informatics System (GIS) remote sensing is the science and art of acquiring information about the earth's surface without actually being in contact with it. GIS is a system for capturing, storing, checking, integrating, manipulating, analyzing and displaying data which are spatially referenced to the earth. The energy source to illuminate a target is in the form of Electromagnetic Waves. Solar radiation incident on objects get reflected and reach the satellite in the passive GIS remote system and satellite is used for both incident and reflected waves in the passive system.”

S.Raghavan, Professor, Electronics and Communication Engineering, National Institute of Technology – Tiruchi (NIT-T), said in his ‘overview talk' that Indian Remote Satellite (IRS) of Indian Space Research Organisation (ISRO) with ten satellites in operation was the world's largest civilian remote sensing satellite constellation. Election commission of India has recently adopted GIS, he said, adding that the impact of GIS on the medical application was tremendous.

N.Anantharaman, Dean – Academic, NIT-T; and N.Sridhar, Honorary Secretary, Institute of Engineers, Tiruchi Chapter, also spoke.
