About the training We are organising a two-day workshop in collaboration with the NASA SERVIR Applied Sciences Team (AST) to introduce the HydroSAR service with its HYDRO30 surface water extent and FD30 flood water depth products. The workshop will also include an introduction to the visualisation properties and a step-by-step methodology for accessing the products via a web-based application. Objectives Provide information on the properties, capabilities, and limitations of the HydroSAR HYDRO30 and FD30 data products Hands-on training on the web application Training on how to download HydroSAR data products via the ICIMOD Regional Database System (RDS) portal Discussion and feedback on the customisation of the web application Outcome By the end of the workshop, participants will have sufficient understanding of the capabilities of the surface water mapping products included in the HydroSAR service and will be able to confidently use the associated web application.

Following the onset of flooding, remotely-sensed geospatial data serves as a critical resource for surface inundation information that can be combined with other social and infrastructure information to aid in disaster response efforts and decision making. In collaboration with a team led by NASA SERVIR Applied Sciences Team member Franz Meyer, Professor, University of Alaska Fairbanks, we developed the cloud-based automatic flood monitoring service HydroSAR, which includes a 30-m surface water extent mapping (HYDRO30) product and a flood water depth (FD30) product, both derived from weather-independent Sentinel-1 SAR data. The products are available within hours after data acquisition and can provide near real-time information on flood water extent and depth as an event progresses. The products are available for the lower reaches of the HKH region and are distributed via a web service through our (RDS) portal.
