DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery
Remote Sensing in Ecology and Conservation, EarlyView.Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...

UAVs unveil the role of small scale vegetation structure on wader nest survival
Remote Sensing in Ecology and Conservation, EarlyView.In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Remote Sensing in Ecology and Conservation, EarlyView.The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

Kıyı bölgelerde Klasik-RTK ve Ağ-RTK ölçme yöntemlerinin karşılaştırılması
, 2023 Since the beginning of human life, human beings have wanted to know their position and have therefore tried to find out where they are and where they are going. Researches and inventions that have shaped this situation have followed one another. The most remarkable of these inventions is GPS (Global Positioning Systems). Positioning by satellites later

Using time‐series remote sensing to identify and track individual bird nests at large scales
Remote Sensing in Ecology and Conservation, EarlyView.Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Modified RTK-GNSS for Challenging Environments
SensorsReal-Time Kinematic Global Navigation Satellite System (RTK-GNSS) is currently the premier technique for achieving centimeter-level accuracy quickly and easily. However, the robustness of RTK-GNSS diminishes in challenging environments due to severe multipath effects and a limited number of available GNSS signals.
