    • Lake Bathymetry Maps derived from Landsat and Random Forest Modeling, North Slope, AK

    Metadata Updated: July 10, 2025

    This dataset provides lake bathymetry maps derived from Landsat surface reflectance products for a portion of the North Slope area of Alaska. A random forest regression algorithm was used to generate depths for each point identified as being part of a lake, creating depth prediction files for each Landsat scene available for the study period: 2016-07-01 to 2018-08-31. These products are fitted to the ABoVE standard projection and reference grid to make them easily scalable and geometrically compatible with other products in the ABoVE study ___domain. The data are provided in cloud-optimized GeoTIFF (COG) format.
