Estimation 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 کاملAssessing the quality of permanent sample plot databases for growth modelling in forest plantations
Informed plantation management requires a good database, since the quality of information depends on the quality of data, growth models and other planning tools. There are several important questions concerning permanent plots: how many plots, where to put them, and how to manage them. Plot measurement procedures are also important. This paper illustrates graphical procedures to evaluate existi...
متن کاملForest Structure and Tree Recruitment Changes on a Permanent Historical Cinder Hills Plot Over a 130-Year Period
We examined forest structure, tree recruitment, and spatial pattern over a 130-year period on cinder soils in northern Arizona. Data were collected from a 3.24 ha permanent, stem-mapped plot established in 1909. This site is unique in that it represents ponderosa pine (Pinus ponderosa Laws. var. scopulorum Engelm.) growing on black cinder soils, which are of limited extent in the Southwest. Tre...
متن کاملGetting the most out of your permanent plot data
A catalogue of ideas for graphical analyses of growth data is presented, in the hope of stimulating the more imaginative analyses. Graphs can be particularly revealing, because the human eye is good at detecting patterns. Suggestions are given to make graphs more effective, and analyses more insightful.
متن کاملAn integrated system for 3D tree modeling and growth simulation
Virtual Geographic Environments (VGEs) represent a new analytical tool for understanding geographic processes. Among the fundamental solutions to advancing and deepening the development of VGEs are geographic modeling, geographic simulation, and geographic knowledge sharing. Forest is a major component of the geographic environment. This article proposes an integrated approach for analyzing and...
