Shapefiles Defining Areas of Analysis for Proglacial Sediment Studies on Mount Rainier, 1960 to 2017
This repository contains suites of shapefiles defining areas of analysis used in Anderson and Shean (2021). Three types of shapefiles are included, each bundled into a zip file: First, polygons delineating areas with elevation changes we judge to be overwhelmingly due to sediment motion (as opposed to snow or ice melt), used to calculate final volumes of change reported in Anderson and Shean (2021). File names indicate basin and DoD interval associated with a given polygon. Second, polygons defining areas used for averaging Landsat NDVI values. Third, regular valley-spanning cross sections used to calculate longitudinal profiles of the valley floors over time. Calculating the minimum elevation across these cross sections using the DEMs provided elsewhere in this repository will exactly reproduce results presented in Anderson and Shean (2021). These shapefiles include an attribute table indicating both the distance from the start of the centerline (shp_dist) as well as distance relative to Little Ice Age glacial maxima (lia_dist).
