UAV-borne lidar campaign over Umiuaq, Hudson Bay, Canada in 2017 and 2018 ...

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)....

Description
Summary: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. ... : We provide the DSM and DTm files as geotiffs for ease of use. DSM_winter_3cm_NORTH.tif DSM_summer_3cm_NORTH.tif DTM_winter_3cm_NORTH.tif DTM_summer_3cm_NORTH.tif DSM_winter_3cm_SOUTH.tif DSM_summer_3cm_SOUTH.tif DTM_winter_3cm_SOUTH.tif DTM_summer_3cm_SOUTH.tifThe filenames are split into 4 parts:XXX_yyy_zzz_www.tifXXX = Either DSM or DTM. For summer images, DSM corresponds to the surface elevation including vegetation and DTM to the surface elevation with the vegetation cover removed. For winter images, DSM corresponds to the elevation of the snow surface and vegetation sticking out of the snowpack, and DTM to the elevation of the snowpack with the vegetation ignored.yyy = Either summer or winter. Summer corresponds to the snow-free acquisitions on the 28-29 September 2017. Winter denotes the snow-covered acquisitions acquired on 25-26 April 2018.zzz = 3cm. The spatial resolution of the dataset.WWW = Either SOUTH or NORTH. Indicates which site the survey was performed over.The data are projected in EPSG: ...
