About this Event

From California to Cambodia - Surface Water Mapping Using Cloud-Based Remote Sensing (by Christopher Soulard, USGS Research Geographer)

  • With cloud based remote sensing we can now access, process, and analyze terabytes of satellite imagery remotely via the internet.
  • Satellite images and streamgages are the two most common measurement tools used to assemble a record of historical surface water changes.
  • Weekly to monthly snapshot of surface water from satellite images can identify the extent of discrete flooding events.
  • These maps, along with climate records, enable us to better understand how precipitation events contribute to the timing, location, and extent of flooding and drought.
