This dataset was created to assess regions and watersheds of Alaska for mean elevation, minimum elevation, maximum elevation, median elevation, standard deviation of elevation, range of elevation and coefficient of variation of elevation in each SASAP region and each HUC8 watershed of Alaska. Three DEM's were mosaicked to make an Alaska-wide tiff. These include separate files for Alaska, the Yukon, and British Columbia. They were combined with the "sasap_regions.zip" shapefile (Jared Kibele and Jeanette Clark. 2018. State of Alaska's Salmon and People Regional Boundaries. Knowledge Network for Biocomplexity. doi:10.5063/F1125QWP) to create the shapefile, "regions_elevation_shp.zip" and with the "sasap_watersheds_gapfix.zip" shapefile (Jared Kibele. 2018. Hydrologic Unit (HUC8) Boundaries for Alaskan Watersheds. Knowledge Network for Biocomplexity. doi:10.5063/F1Q52MV3.) to create the shapefile "watersheds_elevation_shp.zip". CSV versions of the resulting shapefiles are also archived. The included jupyter notebook which was used to merge the data, outlines the process in more detail. The included RMarkdown document is used to generate region and statewide figures for elevation, utilizing a set of functions written to map data for the SASAP project (Jeanette Clark, Rachel Carlson, and Jared Kibele. General mapping functions for data associated with the State of Alaska's Salmon and People (SASAP) project, 2019. Knowledge Network for Biocomplexity. doi:10.5063/F1Z31WXD).
