Geospatial Technology and Outreach Programme Group (GT&OP Group)

Geospatial Technology and Outreach Programme (GT&OP) Group: GT&OP Group consists of three technology departments at IIRS namely Photogrammetry & Remote Sensing, Geoinformatics and Geo-web services, IT & Distance learning department. This is a technology group who deals with various technological aspects and outreach activities of the Institute. The group conducts various education and training programmes and research projects related to geospatial technology developments, aerial and terrestrial photogrammetry, soft computing, advance digital image processing, UAV remote sensing, Microwave and hyperspectral remote sensing, spatial data processing and analysis techniques, Mobile GIS and location based services, crowdsourcing and participatory GIS, Web services and cyber GIS infrastructure development, spatial DBMS, sensor web, High performance computing etc. The group is also responsible for IIRS-ISRO Outreach programme. Under outreach activity, the online learning platforms are being developed for various applications of remote sensing and geospatial technologies. The online courses are available in two modes i.e. live & Interactive (also known as EDUSAT) and e-learning.
