Catch Up on SAR and NISAR for Flood Monitoring
Interested in learning about synthetic aperture radar (SAR) and the NASA-ISRO Synthetic Aperture Radar (NISAR) mission? Check out this wealth of information, shared by NISAR experts at EOTEC DevNet’s January 21/22 regional flood working group meet-ups.
Across the four regional exchanges, presentations centered on:
- NISAR capabilities for flood inundation mapping
- Insights on the evolution of SAR and potential for future use
- Three regionally-specific demonstrations using Sentinel-1 radar images for flood mapping on Google Earth Engine (GEE)
- ISRO’s uses of SAR and optical imagery for maps and support to early warning systems, damage assessment, and capacity building during the flood season
- Ongoing work on an intercomparison of global products across five different flooding events
Presenters included:
- Erika Podest, NASA Jet Propulsion Laboratory, NISAR Science Team
- Cathleen Jones, NASA Jet Propulsion Laboratory, NISAR Applications Lead
- CM Bhatt, Indian Space Research Organisation
- Maynard Micky Maganini, NASA EarthRISE, University of Alabama Huntsville
- Guy Schumann, CEO of RSS-Hydro SARL
