Development of image analysis techniques to enable low-cost tropical rain forest monitoring
Tropical rain forests are important carbon stores and harbours of biodiversity but are being cleared at an unprecedented rate. There is an estimated 2 billion hectares of degraded forest globally, which retains a large proportion of its biodiversity. Restoration of these lands is needed to meet …

Tree-Level Forest Monitoring with Artificial Intelligence Using Neural Networks and High-Resolution Imagery
Mapping and monitoring tree crowns provides vital information on the earth's changing climate. We can use tree measurements to quantify the biomass and stored carbon in a forest, we can use those measurements to inform plantation management on harvest cycles, we can even use tree measurements to …

Fidelity versus Scalability: Deep Learning in Forest Remote Sensing
Climate change drives complex responses in forest ecosystems, with individual trees responding differently depending on species, size, and local competition. These individual responses to stressors such as drought and temperature can drastically alter forest composition, and cannot be captured …

Using Unmanned Aircraft to Provide Near Real-Time Updates of Biomass, Forest Structure and Land Use in the Western Amazon
… expensive or labor-intensive inventory methods. Forest carbon is a key uncertainty in the global carbon cycle and is important for carbon conservation schemes. State-of-the-art techniques in forest carbon monitoring typically involve the use of accurate but costly manned aircraft to estimate …

Contributions to deconfliction advanced U-space services for multiple unmanned aerial systems including field tests validation
… The main developments of the proposed Thesis are monitoring and tactical deconfliction services, which are in charge of identifying and resolving possible conflicts that arise in the shared airspace of several UAS. By limiting the conflict search to a local search surrounding each waypoint, the …

Sampling strategies for forest aerial detection survey in Colorado
… survey (ADS) has been commonly employed in forest surveys in the United States for detecting forest damage and monitoring forest health. In Colorado, ADS by USDA Forest Service has conducted annual 100% census of government forested land for more than 20 years with the goal of achieving …

Forest and woodland regeneration dynamics and persistence in the human- modified landscape of Greater Gombe Ecosystem, Tanzania
AbstractThe clearing of tropical forests and woodlands for human use puts many species at risk of extinction. Vast areas of forests and woodlands have been converted to fragmented patches located within mosaics of different land uses (e.g., agricultural lands and human settlements). Some …

Wetlands Characterization in the Congo River Basin Using Multi-source Remotely Sensed Data and Field Survey
… This map is then combined with vegetation and forest cover change maps published in Potapov et al. (2012) to derive a map including forested wetlands as a thematic class. Using population density data, we investigated whether high terra firma population density and low percent remaining terra …
