Digital Terrain Models elevation metrics from acquisition in 2022

Digital Terrain Models (DTMs), Slope, Aspect, Topographic Position Index (TPI), curvature in profile and plan direction and their average, and flow accumulation derived from airborne LiDAR data acquired over the Bukit Duabelas, Batanghari regency and Harapan rainforest protected area, in Jambi, Sumatra, Indonesia. Slope, aspect, curvatures, flow accumulation and TPI were calculated following a two-step approach where first the DTM was resampled to 10 m pixel size and then the metrics were calculated and further aggregated to 50 m (see also Jucker et al. 2018 https://doi.org/10.1111/gcb.14415). Original pixel size of DTM: 1m. Geographic Coordinate System: EPSG 32748.
