Estimation of Tropical Forest Height and Aboveground Biomass from Dual-band InSAR measurements in Peruvian Amazon
In July 2009, Earthdata Inc. acquired Synthetic Aperture Radar (SAR) data over a lager part of the Peruvian lowland Amazon and mountain forests (more than 5000 km 2 ). The project was designed to provide high spatial resolution imagery to the science community to estimate and map forest aboveground biomass and to assess the capability of the measurements for REDD baseline applications. GeoSAR c...
متن کاملTropical forest biomass estimation and the fallacy of misplaced concreteness
Tropical forests store an estimated 193–229 Pg of carbon in above-ground biomass (Saatchi et al. 2011; Baccini et al. 2012), or roughly 20 times the annual emissions from combustion and land-use change (Friedlingstein et al. 2010). The quantity of biomass, usually measured in units of mass ha 1 (such as Pg or Mg ha ) varies among continents, regions and landscapes because of climate, disturbanc...
متن کاملEstimation of tropical forest height and biomass dynamics using lidar remote sensing at La Selva, Costa Rica
[1] In this paper we present the results of an experiment to measure forest structure and biomass dynamics over the tropical forests of La Selva Biological Station in Costa Rica using a medium resolution lidar. Our main objective was to observe changes in forest canopy height, related height metrics, and biomass, and from these map sources and sinks of carbon across the landscape. The Laser Veg...
متن کاملEstimation of Tree Biomass at Individual tree, Sample plot and Hybrid Level using Drone Images
Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...
متن کاملSmall-footprint lidar estimation of sub-canopy elevation and tree height in a tropical rain forest landscape
Meso-scale digital terrain models (DTMs) and canopy-height estimates, or digital canopy models (DCMs), are two lidar products that have immense potential for research in tropical rain forest (TRF) ecology and management. In this study, we used a small-footprint lidar sensor (airborne laser scanner, ALS) to estimate sub-canopy elevation and canopy height in an evergreen tropical rain forest. A f...
