Confluence Retirement

Due to the feedback from stakeholders and our commitment to not adversely impact USGS science activities that Confluence supports, we are extending the migration deadline to January 2023.

In an effort to consolidate USGS hosted Wikis, myUSGS’ Confluence service is targeted for retirement. The official USGS Wiki and collaboration space is now SharePoint. Please migrate existing spaces and content to the SharePoint platform and remove it from Confluence at your earliest convenience. If you need any additional information or have any concerns about this change, please contact Thank you for your prompt attention to this matter.

Subject: National Innovation Center Seminar - Thursday, March 12 @ 10:30 am - Automatic satellite-based flood mapping for disaster response

Dear Colleagues,

Please join us next Thursday, March 12 @ 10:30 am for the National Innovation Center Seminar with our NASA/USGS Postdoctoral Researcher Dr. Liz Carter at USGS Moffett Field, Building 19, Yosemite Conference Room (2nd Floor, Room 2030A). Dr. Carter will be discussing her project to automate satellite-based flood mapping for disaster response. 

As flood events are becoming more frequent and more severe, the impacts of flooding on a growing and urbanizing domestic population have intensified. The last four decades have brought significant increases in flood related deaths, size of flood-affected population, and flood associated economic damages. To mitigate the societal impacts of flooding, access to reliable, real-time information on flood-affected areas has proven critical for coordinating efficient inter-agency disaster response. Multiple challenges have limited the adoption of satellite-based flood mapping in disaster response, including: lack of available imagery at exact time/location of flood event; computational limitations to storage/processing of large spatial data sets; and challenges associated with automatic classification of flooded pixels (i.e. lack of available ground-truthing for model training and limitations to quantifying classification uncertainty). This presentation will provide an overview to a joint USGS-NASA-NGA-Univ. Alabama initiative to develop a platform for automatic near-real time flood detection, using multiple sources of satellite imagery for use in disaster response. The platform will be based on an open-source library for supervised classification of satellite radar and optical imagery using deep neural networks currently under development at the NASA Ames and USGS Innovation Center at Moffett Field, CA.

The talk will be livestreamed:
