Data Description
UAV data was acquired over the regions of the two trails in the military reserve as well as field surveys of the seedling’s survival status and treatment type. The UAV was flown at 110m height above the AGL at a steady speed of 12 m/s. It takes about 11min to cover the 11.8 Hectare area. A total of 102 images were acquired with more than 70% side and along and across track overlap. The UAV data was acquired in JPEG format with Phantom 4 Pro V2.0, a high-performance drone specifically designed for aerial imaging and data collection applications. 8 Ground Control Points (GCPs) uniformly distributed around the project domain were also acquired using high precision GPS equipment. 5 of these GCPs fall within the survey domain that we are processing for this project. Two of the GCPs are located around the east edge of the domain, two along the center and one along the west edge. Seedlings survey data was also acquired close in time with UAV data acquisition (plant_survey_points.csv). Data collected include survival status (survived or otherwise), treatment type (Mulch, protected, none) and point location. A total of 154 seedling data was acquired.
There is also a lidar point cloud over a subset of the study area. The data was downloaded from open topography portal.
