Integration of Lidar, Landsat Etm+ and Forest Inventory Data for Regional Forest Mapping
Recent work has established the utility of waveform sampling lidar for predicting forest structural attributes. Nevertheless, serious obstacles to its wide-spread use still exist. They include the lack of waveform sampling lidar sensors capable of measuring forest canopy structure over large extents, and the practical difficulty of developing widely applicable relationships to predict forest st...
متن کاملMapping Global Forest Aboveground Biomass with Spaceborne LiDAR, Optical Imagery, and Forest Inventory Data
As a large carbon pool, global forest ecosystems are a critical component of the global carbon cycle. Accurate estimations of global forest aboveground biomass (AGB) can improve the understanding of global carbon dynamics and help to quantify anthropogenic carbon emissions. Light detection and ranging (LiDAR) techniques have been proven that can accurately capture both horizontal and vertical f...
متن کاملEstimating aboveground biomass using Landsat 7 ETM+ data across a managed landscape in northern Wisconsin, USA
Aboveground biomass (AGB; Mg/ha) is defined in this study as a biomass of growing stock trees greater than 2.5 cm in diameter at breast height (dbh) for stands N5 years and all trees taller than 1.3 m for stands b5 years. Although AGB is an important variable for evaluating ecosystem function and structure across the landscape, such estimates are difficult to generate without high-resolution sa...
متن کاملModeling Forest Aboveground Biomass and Volume Using Airborne LiDAR Metrics and Forest Inventory and Analysis Data in the Pacific Northwest
The United States Forest Service Forest Inventory and Analysis (FIA) Program provides a diverse selection of data used to assess the status of the nation’s forests using sample locations dispersed throughout the country. Airborne laser scanning (ALS) systems are capable of producing accurate measurements of individual tree dimensions and also possess the ability to characterize forest structure...
متن کاملAboveground Forest Biomass Trends for the Conterminous U.s. Inferred from Landsat Time-series and Field Inventory Data
We used a sample of Landsat time-series stacks (LTSS) across the conterminous U.S., calibrated with Forest Inventory and Analysis (FIA) plot-level biomass data to estimate 20+ year trends in live, aboveground biomass. To help overcome some of the limitations associated with optical remote sensing of biomass stocks, we employed a pixel-level curve-fitting algorithm to leverage the information co...
