资源简介：
This geospatial dataset is based on the National Hydrographic Dataset (NHD) Model (v2.2) for Alaska published on May 27 2014. For each waterbody, we established a unique ID and calculated fetch distance in meters (m) using the lakemorpho package in R. Fetch is the maximum distance or the longest open water distance across a body of water. We used 200 points along the waterbody shore to determine the fetch. The dataset also contains information on the elevation of each waterbody. A 60m digital elevation model (DEM) was used to calculate the maximum elevation point within the water body using zonal statistics in ArcMap 10.7.
