Tropical Peatland Burn Depth and Combustion Heterogeneity Assessed Using UAV Photogrammetry and Airborne LiDAR

TL;DR: This approach provides significant uncertainty reductions in such emissions calculations via the reduction in DoB uncertainty, and by using the UAV SfM approach this is accomplished at a fraction of the cost of airborne LiDAR—albeit over limited sized areas at present.
Journal ArticleDOI
Assessment of Errors Caused by Forest Vegetation Structure in Airborne LiDAR-Derived DTMs
TL;DR: The need for adequate ground control schemes to accompany any forest-based airborne LiDAR survey which require highly accurate DTMs is highlighted, particularly in relation to analysis of pre- and post-burn surface height maps used to quantify the combustion of organic soils.
Journal ArticleDOI
High Spatial and Temporal Resolution Energy Flux Mapping of Different Land Covers Using an Off-the-Shelf Unmanned Aerial System
Jake E. Simpson,Fenner Howard Holman,Hector Nieto,Ingo Voelksch,Matthias Mauder,Janina Klatt,Peter Fiener,Jed O. Kaplan +7 more
TL;DR: In this paper, the authors present an empirical method for calibrating airborne radiometric temperature in standard units (K) using the Altum multispectral and thermal infrared instrument using the two-source energy balance model (TSEB) for mapping net radiation (Rn), sensible (H), latent (LE) and ground (G) heat fluxes at <082 m resolution, with root mean square errors (RMSE) less than 45, 37, 39, 52, 52 W m−2 respectively.
