Landsat Imagery-Based Above Ground Biomass Estimation and Change Investigation Related to Human Activities
Forest biomass is a significant indicator for substance accumulation and forest succession, and a spatiotemporal biomass map would provide valuable information for forest management and scientific planning. In this study, Landsat imagery and field data cooperated with a random forest regression approach were used to estimate spatiotemporal Above Ground Biomass (AGB) in Fuyang County, Zhejiang P...
متن کاملAbove Ground Biomass estimation from SAR vertical reflectivity profiles
First attempts for the estimation of above ground forest biomass (AGB) by means of SAR, have used allometric equations to calculate biomass from the estimated PolInSAR forest height. However, changes in forest density or structure bias the known allometric relations. Today, remote sensing systems like SAR are able to measure additional parameters like vertical forest structure [1] [2]. In this ...
متن کاملExamining Spectral Reflectance Saturation in Landsat Imagery and Corresponding Solutions to Improve Forest Aboveground Biomass Estimation
The data saturation problem in Landsat imagery is well recognized and is regarded as an important factor resulting in inaccurate forest aboveground biomass (AGB) estimation. However, no study has examined the saturation values for different vegetation types such as coniferous and broadleaf forests. The objective of this study is to estimate the saturation values in Landsat imagery for different...
متن کاملAbove-Ground Biomass and Biomass Components Estimation Using LiDAR Data in a Coniferous Forest
This study aims to estimate forest above-ground biomass and biomass components in a stand of Picea crassifolia (a coniferous tree) located on Qilian Mountain, western China via low density small-footprint airborne LiDAR data. LiDAR points were first classified into ground points and vegetation points. After, vegetation statistics, including height quantiles, mean height, and fractional cover we...
