Presented here is the final dataset accompanying the publication, ,"Accuracy Assessment of Late Winter Snow Depth Mapping for Tundra Environments Using Structure-From-Motion Photogrammetry" submitted to Arctic Science, in Spring 2020. Included within are seven Structure-from-Motion (SfM) photogrammetry snow depth maps produced using a fixed-wing Unmanned Aerial System (UAS) and the methods described within the corresponding manuscript. In situ observations of snow depth collected using a Magnaprobe snow depth probe and snow-surface elevations are also included in separate CSV files and represent the final dataset used for ground validation during the 2018 March and April field campaigns at Trail Valley Creek, Northwest Territories, Canada. A readme file is included containing important information on data collection, processing and QA/QC including UAS flights protocol, RTK GNSS benchmark coordinates and elevation datum, and processing steps for each snow depth map presented.
