A Photogrammetric Workflow for the Creation of a Forest Canopy Height Model from Small Unmanned Aerial System Imagery
The recent development of operational small unmanned aerial systems (UASs) opens the door for their extensive use in forest mapping, as both the spatial and temporal resolution of UAS imagery better suit local-scale investigation than traditional remote sensing tools. This article focuses on the use of combined photogrammetry and “Structure from Motion” approaches in order to model the forest c...
متن کاملA Geobia Approach to Estimate Large Area Forest Canopy Height Using Lidar Transects and Quickbird Imagery
Numerous applications of small footprint airborne lidar (light detection and ranging) have provided highly accurate results for estimating forest height. However, the associated acquisition cost remains high, which limits its use for wall-to-wall large area mapping. In this study, we developed a novel framework by integrating GEOBIA (GEOgraphic Object-Based Image Analysis), lidar transects and ...
متن کاملAn Unmanned Aerial Vehicle Based Forest Patrol System
Although technology has advanced at breathless pace, wildfire still bursts out every year all over the world. There are various wildfire monitoring system employed in diferrent countries, most of them are depended on photos or videos to identify features of wildfire, after wildfire happened. Delay of confirmation is diverse based on used techonologies. An autonomous forest patrol system by Unma...

متن کاملComplementing Forest Inventory Data with Information from Unmanned Aerial Vehicle Imagery and Photogrammetry
Although a prerequisite for an accurate assessment of tree competition, growth, and morphological plasticity, measurements conducive to three-dimensional (3D) representations of individual trees are seldom part of forest inventory operations. This is in part because until recently our ability to measure the dimensionality, spatial arrangement, and shape of trees and tree components precisely ha...
