Soil Adjusted Vegetation Index (SAVI) for a site on the Seward Peninsula, Alaska collected on August 14, 2018. SAVI is similar to NDVI, but it suppresses the effects of soil pixels and it uses a canopy background adjustment factor. The reflectance data used to calculate SAVI was collected by the AVIRIS-NG instrument on a flight over the Seward Peninsula, Alaska, on August 14, 2018.

Body

New AVIRIS-NG data from the 2018 ABoVE airborne campaign and an accompanying data processing tutorial are now available.

Riverbank erosion and vegetation colonization at the Yukon River 1 study area, located along the Middle Yukon River between Circle and Fort Yukon, Alaska, from 1985-2017.

Body

Research from NASA's ABoVE campaign provides a record of riverbank erosion and vegetation colonization along major Alaskan rivers from 1984 to 2017.
