Ice-Wedge Network Centerline and Polygon Area in the Bernard River Watershed, Banks Island Canada; 2010-2020

This dataset accompanies the commentary submitted to Nature: "The Capillaries of the Arctic Tundra" (Liljedahl, A., Witharana, C., and Manos, E., 2024). Code can found at https://github.com/PermafrostDiscoveryGateway/IWP-Network-Extraction. This dataset contains two second generation products derived from ice-wedge polygons (IWPs) mapped at the pan-Arctic scale from sub-meter spatial resolution Maxar satellite imagery (Witharana et al. 2023). Both products are derived using IWPs mapped from Maxar satellite imagery acquired over the Bernard River Watershed in Banks Island, Canada from 2010-2020:
(1) Polyline shapefile of ice-wedge centerlines estimated via basic spatial analysis. These lines represent the total length added to the tundra capillary system if all the mapped ice wedges were to degrade and form a connected network of trough-channels (i.e., capillary hydrological system).
(2) Polygon shapefile of IWP area and percentage of land cover within 1 kilometer (km) x 1 km rectangular grid cells covering the Bernard River Watershed.
