资源简介：
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 (located here: https://knb.ecoinformatics.org/#view/urn:uuid:2c1c26fc-bfb9-4b6a-8d4a-0be8e61c4deb) to create
the shapefile, "regions_elevation_shp.zip"
and with the "sasap_watersheds_gapfix.zip" shapefile (located here: https://knb.ecoinformatics.org/#view/urn:uuid:2b5ab57e-38ec-4bc9-8290-f080ec0befb4)
to create the shapefile "watersheds_elevation_shp.zip".
CSV versions of the resulting shapefiles are also archived.
The included python script, which was used to merge the data, outlines the process in more detail.
