Description

This dataset provides a time series of riverbank erosion and vegetation colonization changes along reaches of the Yukon River (3 study areas), the tributary Tanana and Nenana Rivers (1 area), and the tributary Chandalar River (1 area) in interior Alaska over the period 1984-2017. The change data were derived from selected 30-m images from Landsat TM, Landsat ETM+, and Landsat Operational Land Imager (OLI) surface reflectance products. Image classification used the Normalized Differenced Vegetation Index (NDVI) with an NDVI threshold of 0.2 to differentiate vegetated from non-vegetated pixels. Images were assigned to one of seven or eight multiyear intervals, within the 1984-2017 overall range, for each study area. Time intervals vary by study site. Change detection looked for shifts over one time interval to the next interval; changes from vegetated to non-vegetated were considered riverbank erosion and changes from non-vegetated to vegetated were considered vegetation colonization.
