Abstract:
This dataset presents Harmonized Landsat Sentinel-2 and SAR Sentinel-1 tiles labeled with forest structural information at 86 sites (minimum 50 m by 500 m) in the boreal forests of Alaska and Northwest Canada. UAV-LiDAR data was collected at each site between 2022 and 2024. Canopy height and crown coverage were derived from the point clouds. The HLS pixels were collected as time series for two seasons: peak summer (June 20th to August 10th 2022, 2023, 2024) with 648 tiles, and late summer (August 20th to September 30th, 2022, 2023, 2024) with 258 tiles. We applied a 30 % cloud cover filter and masked remaining clouds, water bodies, and snow with the HLS Fmask bit filters. We computed and added one NDVI band per season. The Sentinel-1 data (VV, VH, angle) were collected for the same seasons (peak and late summer) and pre-processed following Mullissa et al. 2021 (https://doi.org/10.3390/rs13101954 ; https://github.com/adugnag/gee_s1_ard) in python and Google Earth Engine). The median pixel value of HLS and S-1 was taken from the median composites at each site. We resampled the crown coverage and median canopy height with the HLS grid resolution (30 m) and stacked the rasters together.
