In 2015 the U.S. Geological Survey, Pacific Coastal and Marine Science Center, in cooperation with the Alaska Department of Fish and Game (ADFG), collected bathymetry and acoustic-backscatter data near Cross Sound in southeast Alaska using a Reson 7111 multibeam echosounder mounded to the ADFG R/V Solstice. The bathymetry and acoustic-backscatter data are provided as GeoTIFFs with 10-m...
Burn Severity Portal, a clearing house of fire severity and extent information (ver. 11.0, April 2025) Burn Severity Portal, a clearing house of fire severity and extent information (ver. 11.0, April 2025)
The various post-fire data products available on the Burn Severity Portal are produced using satellite imagery. The timing of the satellite imagery used, relative to the fire event, typically depends on the vegetation type and structure where the fire occurred. Each mapping program produces a suite of data products based on user intended user needs. You can find additional details in...
