Distribution and morphometry of pingos, western Canadian Arctic, Northwest Territories, (CA)

Wolfe, Stephen; Morse, Peter; Parker, Ryan; Phillips, Marcus

GIS shape files including spatial and morphometric data of pingos in the western Canadian Arctic and accompanying Excel spreadsheet summarizing metrics for pingos of differing height categories. Within ArcGIS®, the pingo database of Wolfe et al. (2021) and HRDEM (Natural Resources Canada, 2020) were used to determine pingo metrics, including top and base elevations, planimetric (“footprint”) area, slope, surface area, ratio of the surface area to base area (i.e., surface ratio), and volume. Pingos were seperated into categories of 0.6 to 2.0 m, and >2.0 m high. Metrics were determined with use of custom algorithm implemented as a Python script utilizing the ArcPy library and DEM Surface Tools extension (Jenness, 2010) for ArcGIS® DesktopTM 10.7.1. Detailed methodology may be found in the accompanying paper.
