UAV-Based Slope Mapping Accuracy at Different Flight Altitudes Using Minimum Ground Control Point Configurations
This study evaluates the accuracy of Unmanned Aerial Vehicle (UAV)-based slope mapping at different flight altitudes using minimal Ground Control Point (GCP) configurations. Two 3-GCP arrangements, namely diagonal top-to-bottom and straight top-to-bottom, were first compared using Real-Time Kinematic (RTK)-based cross-...
