Summary: | This dataset was created to identify the dominant rock type of each SASAP region and each HUC8 watershed of Alaska. The Global Lithology Map (GliM) from the University of Hamburg (Hartmann, Jörg; Moosdorf, Nils (2012): Global Lithological Map Database v1.0 (gridded to 0.5° spatial resolution). PANGAEA, https://doi.org/10.1594/PANGAEA.788537, License: Creative Commons Attribution 3.0 Unported) was combined with the "sasap_regions.zip" shapefile (located here: https://knb.ecoinformatics.org/#view/urn:uuid:2c1c26fc-bfb9-4b6a-8d4a-0be8e61c4deb) to create "Lithology_shp_regions.zip", a shapefile that contains measurements of the area covered by certain lithologies in each SASAP region. It was also combined with the "sasap_watersheds_gapfix.zip" shapefile (located here: https://knb.ecoinformatics.org/#view/urn:uuid:2b5ab57e-38ec-4bc9-8290-f080ec0befb4) to create "Lithology_shp_watersheds.zip", a shapefile that contains measurements of the area covered by certain lithologies in each Alaskan watershed. 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.
