I connect social and environmental questions with spatial evidence: forest-fire prediction, glacial-lake hazards, malaria hotspots, food security, ethnobotanical relationship and regional development. This site collects the open-source tools and open data I use and teach, and includes a free WebGIS for Indian topographic sheets.
I am a geographer and geospatial analyst. My work joins remote sensing and GIS to regional development, public policy, food security, health, traditional medicine, disaster management, economics and the study of human impact on the environment as well as DGCA Certified Drone Pilot (RPC)
I work in open-source GIS, professional GIS and WebGIS. As JNU coordinator for the IIRS-ISRO outreach programme I have coordinated 141 geospatial courses, from GNSS basics and SAR to AI/ML for Geodata Analysis. I have worked as a consultant for UNFPA, ISI Delhi, IIHMR, the HP State Disaster Management Authority, Save the Children, The United Nations and many more....
