V. N. d'  aImpacts of selective logging on Amazon forest canopy structure and biomass with a LiDAR and photogrammetric survey sequence.h[electronic resource]  c2021  aThe aim of this paper was to verify the potential of combining a multitemporal sequence of ground data, airborne LiDAR, and 3D photogrammetry, to monitor forest disturbance after reduced-impact selective logging. Our specific objectives were to (i) estimate structural changes in the forest canopy produced by logging operations (roads, log landings, felled tree gaps and skid trails), (ii) develop and verify the consistency of two AGB models, one produced by height metrics derived from LiDAR data alone, and the second by a combination of the LiDAR-derived DTM and a photogrammetry-derived DSM, and (iii) to upscale the developed AGB models from plot to local level to estimate the AGB stocks before and after logging, and infer subsequent AGB loss.  aAboveground biomass  aEnvironmental impact  aForest canopy  aLidar  aLogging  aPhotogrammetry  aSustainable forestry  aUnmanned aerial vehicles  aAerofotogrametria  aBiomassa  aExploração Florestal  aExtração da Madeira  aImpacto Ambiental  aAcre  aAeronave remotamente pilotada  aAmazonia Occidental  aAmazônia Ocidental  aBiomasa aérea  aCubierta forestal  aDossel  aDrone  aExplotación forestal  aFLoresta Estadual do Antimary (AC)  aRGB images  aSena Madureira (AC)  aSilvicultura sustentable  aVehículos aéreos no tripulados  aWestern Amazon1 aFIGUEIREDO, E.
