Earth-Observsing remote sensing data is critical for mapping and understading earth processing. Small unmanned aerial systems (sUAS) are revolutionizing remote sensing, offering unparalleled flexibility and precision.  Data retrieved from these platforms for validating remote sensing data collected from space, or can serve as analouges for spaceborne remote sensing.  The 3DGL Drone Lab at the Center for Space Research houses a fleet of medium- and heavy-lift drones equipped with lidar and electro-optical payloads.  This technology enables the lab to capture a wide range of environmental features, from measuring forest structure to creating bathymetric profiles, supporting diverse applications. 

3D Data Collection

The 3DGL has extensive experience in collecting and processing high-resolution and high-accuracy 3D geospatial data. We specialize in sUAS photogrammetry, sUAS lidar, terrestrial laser scanning, and geodetic surveying.

Our goals:

• Collect high accuracy and precision datasets
• Utilize Real-time and post-processed GPS/GNSS solutions along with ground control points to ensure the utmost quality data
• Collect data to assess errors and uncertainties
• Develop strategies for applying Generic Point Model (GPM) errors and uncertainties to high resolution data
