Remote Sensing of Wetlands in the Prairie Pothole Region of North America

Joshua Montgomery, Craig Mahoney, Brian Brisco, Lyle Boychuk, Danielle Cobbaert, Chris Hopkinson
2021 Remote Sensing  
Wetland classification approaches are reviewed, including Decision Trees, Machine Learning, and object versus pixel-based approaches.  ...  Digital Surface Models are also being incorporated in geospatial analyses to separate forest and shrub and emergent systems based on vegetation height.  ...  In general, high accuracy and ultrahigh-resolution imagery are achievable from most UAVs [92] .  ...

Detection of Bark Beetle Disturbance at Tree Level Using UAS Multispectral Imagery and Deep Learning

Robert Minařík, Jakub Langhammer, Theodora Lendzioch
2021 Remote Sensing  
This study aimed to examine the potential of convolutional neural networks (CNNs) for the detection of individual trees infested by bark beetles in a multispectral high-resolution dataset acquired by an  ...  Based on our findings, we conclude that the Nez and Safaugu CNN models are superior to the RF models and transfer learning models for the identification of infested trees and for distinguishing between  ...  Although the ultrahigh resolution (in cm) may seem beneficial, the artificial mapping unit (the pixel) is much smaller than a crown, making the interpretation of the classified map more complicated and  ...
