Dr George Joseph started his research career at the Tata Institute of Fundamental Research (TIFR), Mumbai. He has been at the Space Applications Centre (SAC), Ahmedabad since 1973 where he was instrumental in developing a variety of electro-optical sensors for earth observation which were first of their kind in India. He served SAC in various capacities including as its director from 1994–1998 and has made substantial contributions toward the realisation of various remote-sensing-related activities for shaping the long-term remote sensing programme of ISRO. He has served in a number of national and international committees/organisations—President of Technical Commission-1 of the International Society for Photogrammetry and Remote Sensing (ISPRS) during 1996–2000, Director of the Centre for Space Science and Technology Education in Asia and the Pacific (CSSTE–AP) affiliated to the United Nations during 2006–2009, to name a few. He is a Fellow of a number of national academies and professional bodies and is a recipient of several awards, including the Padma Bhushan in 1999 for his outstanding contributions to remote sensing in India. http://www.profgeorgej.com/

Dr Jeganathan Chockalingam has been working in the field of Geo-spatial Science and Technology since 1993, and possesses extensive teaching and research experience. He started his scientific career at the Regional Remote Sensing Service Centre (RRSSC, ISRO-Dehradun: 1993–1996), then worked at the Indian Institute of Remote Sensing (IIRS, Department of Space, Dehradun: 1996–2008) followed by the University of Southampton, United Kingdom (2008–2011). He has participated and contributed in the development of various RS-GIS educational programs at IIRS. He has also contributed significantly in many National Mission Projects (involving RS-GIS) of ISRO and developed many software packages (SPLAM, STAMP, ADAMS for ISRO, ICIMOD and IWMI, to mention a few). Since 2011, he has been Professor in the Department of Remote Sensing, Birla Institute of Technology, Mesra, Ranchi, India. His main research interests include geoinformatics, geostatistics, space–time dynamics of vegetation, natural resources monitoring and modelling, spatial decision modelling and downscaling. He is the recipient of the Indian National Geospatial Award (2015) and Klaas Jan Beek Award (2003).
