The polyline dataset currently represents 92 climbing routes at Devils Tower National Monument. It was created in ArcGIS Pro Scene 2.2, using an integrated approach combining literature review and collaboration with technical climbing staff. Routes were heads-up digitized over a 3D model of Devils Tower with derived triangulated irregular network (TIN) surfaces created from the DETO Unmanned Aircraft Systems (UAV) Digital Elevation Model (DEM). This dataset utilizes the updated NPS Core Spatial Data Standard Implementation Plan Template dated August 31, 2016. Description last updated November 2018.
