AbstractThis Open File contains a database of 2363 pingos in the Tukoyaktuk Coastlands and adjacent areas of the western Arctic, Northwest Territories, Canada. Pingos were identified through an iterative process using HRDEM and satellite imagery from Google Earth Pro and ArcGIS EarthTM. The resulting database was compared against Smith and Duong's (2012) digital rendering of 1288 pingos from Mackay's (1963) original compilation and relative precision of geo-positioning from both datasets and validation of pingos identified in this study was assessed. Shapefiles include the geographic coordinates and elevations at the summit of identified pingos derived from the HRDEM. A separate dataset of 456 pingo-like features, representing those features initially identified but subsequently rejected as pingos is also included.
Summary(Plain Language Summary, not published)
We mapped 2363 pingos in the Tukoyaktuk Coastlands and adjacent areas of the western Arctic, Northwest Territories, Canada. We identified these through an iterative process using HRDEM and satellite imagery from Google Earth. Shapefile databases include the locational co-ordinates and point elevations of identified pingos derived from the HRDEM.
