Module 5: Geo-informatics and Information Communication Technology in Disasters
Information communication Technology (ICT) and Geo-informatics Technology (GIT) have been widely used in planning, mitigation, and response in the disaster situations. Besides alerting of the crisis ICT can help us in diverse ways some of which includes disaster preparedness through computer, television, radio, HAM radio and community radio, internet, email, mobile, social media, blogging; emergency response applications like distress communication and deploying bio surveillance for critical diseases either in short or long term etc. ICT systems are also used for modelling and predicting outcomes based on real data. Remote sensing provides synoptic as well as repetitive coverage of in particular area. GIS helps us to bring the physical, demographic, social, and other information from a real world system for decision making in disaster situations. Geo-informatics techniques help us in mapping the hazard zonation, vulnerability and risk using remote sensing, GIS, GPS and other secondary information.
