Weighing trees with lasers: terrestrial laser scanner data; Malaysia Sabah Kabili-Sepilok Forest Reserve 20th March 2017
Abstract
This dataset is comprised of raw and proceesed data from the NERC-funded, full waveform terrestrial laser scanner (TLS) deployed on a plot site situated in Malaysia Sabah Kabili-Sepilok Forest Reserve on the 20th March 2017 . The plot site had the following geographical features; Moisture type: Moist, Elevation: Lowland, Edaphic Type: Terra Firme, Forrestry: Old-growth.
The aim of the weighing trees with lasers project is to test if current allometric relationships are invariant across continents, or whether they differ significantly, and require continental level models; quantify the impact of assumptions of tree shape and wood density on tropical forest allometry; test hypotheses relating to pan-tropical differences in observed AGB (Above Ground Biomass) from satellite and field data. It also aims to apply new knowledge to assessing retrieval accuracy of forthcoming ESA BIOMASS and NASA GEDI (Global Ecosystem Dynamics Investigation Lidar) missions and providing calibration datasets; In addition to testing the capability of low-cost instruments to augment TLS data including: UAVs (unmanned aerial vehicle) for mapping cover and canopy height; low-cost lidar instruments to assess biomass rapidly, at lower accuracy.
