Wildland Fire Tree Mortality Mapping from Hyperspatial Imagery Using Machine Learning
نویسندگان
چکیده
The use of imagery from small unmanned aircraft systems (sUAS) has enabled the production more accurate data about effects wildland fire, enabling land managers to make informed decisions. ability detect trees in hyperspatial enables calculation canopy cover. A comparison post-fire cover and pre-fire sources such as LANDFIRE project tree mortality, which is a major indicator burn severity. mask region-based convolutional neural network was trained classify groups pixels orthomosaic acquired with system. classification summarized at 30 m, resulting raster. then compared preceding calculating how much reduced due fire. Canopy reduction allows mapping severity while also identifying where surface, passive crown, active crown fire occurred within perimeter. mapped through this effort lower than Cover product, literature indicated typically over reported. Assessment on reflects observations made both ground truthing efforts well associated sUAS orthomosaic.

متن کاملAn Object-Based Classification Approach in Mapping Tree Mortality Using High Spatial Resolution Imagery
In California, a newly discovered virulent pathogen (Phytophthora ramorum) has killed thousands of trees, including tanoak (Lithocarpus densiflorus), coast live oak (Quercus agrifolia), and black oak (Quercus kelloggii). Mapping the distribution of overstory mortality associated with the pathogen is an important part of disease management. In this study, we developed an object-based approach, i...
