Disaster Management Support

Floods

Flood monitoring, mapping and dissemination to State and Central relief departments and to Ministry of Home Affairs (MHA), GOI is carried out during all major flood and cyclone events and support is provided to disaster management teams in near real time during flood relief and rehabilitations activities.

Satellite data from Indian Remote Sensing Satellites (IRS) and non IRS satellites (with the help of international charter requests) of all possible acquisitions from global satellites with varying spatial resolutions are utilized for flood mapping. Microwave satellite data is of highest use during flood occurrence and recession periods due to the limitations of cloud in optical data during cloudy conditions.

Current and historic flood maps generated for major flood events in the states across country, Flood duration maps, Flood annual layers, Flood Hazard maps and related technical documents are hosted on as Disaster Services (NDEM Public): (Bhuvan-Flood). Flood forecasting is one of the major activities that is initiated with hydrological modeling utilizing high resolution LiDAR DEM, satellite derived land use / land cover information in flood prone river reaches in the country.

National Flood Vulnerability Assessment System on Bhuvan provides scenario of topography, trends in spatial rainfall, spatial runoff, flood vulnerability index across the country at grid level along with few case studies and technical reports.

Cyclones

NRSC is providing the information from various sources viz. MOSDAC, Joint typhoon warning centre, etc, on near real time depiction of cyclone track and generating information on possible severity zones in view of the predicted land fall locations. Mapping of flood inundations due to cyclones is the major activity that is carried out to support the disaster management teams.

Maps and Information generated during recent cyclone events e.g. Gaja, Titli, Vardah,Nada, Nilofer, HudHud, Phailin are hosted on Bhuvan. Mobile applications were developed for facilitating geo tagging of several damaged assets and incident reporting. They were used for field reporting during HUDHUD cyclone. These are meant for utilization by the State Governments and view the data on Bhuvan for analysis

Forest Fire

Satellite based forest fire monitoring is one of disaster support activity from NRSC for providing timely information on forest fires locations to State Forest Departments across India to trigger the forest fire control and management activities. Active forest fire monitoring uses satellite data from MODIS flying on the TERRA and AQUA spacecraft and Visible Infrared Imaging Radiometer Suite data from the Suomi National Polar- orbiting Partnership (SNPP-VIIRS).

Satellite data is received and processed at Data processing Centre of NRSC in near real-time and information is made available to users (FSI, state forest departments) within 30 minutes of completion of satellite data acquisition. Near real time space based information on active fires, fire burnt area and forest fire regimes during the past decade are provided.

Forest fire alerts are simultaneously web-published through Bhuvan porta. The most recent active forest fire locations and history since 2001 can be visualized through Bhuvan-Forest Fire Alerts. Near real time information on number of forest fires and locations is the key input for the forest department for taking up fire control measures. Forest fire regime analysis is also possible with the archived forest fire location database generated by NRSC.
