We performed high-resolution snow height measurements using drone-based lidar over two 0.5 km long areas near the community of Umiujaq, in Tasiapik valley. The North site is centered around (N:56.5684°; W:76.4895°, elevation 122 m) and the South site around (N:56.5594°; W:76.4816°, elevation 133 m). A snow-free survey was performed on 28-29 September 2017 and a snow survey on 25-26 April 2018. We produced 3 cm digital terrain and digital surface models (DTM and DSM) from the lidar cloud points for each site for both lidar campaigns.
