    Solution: Multi-Look and Oversampling

  • | 8 Airborne Geiger Mode LiDAR Technology to Connect, Inform and Protect TM

    What makes Geiger Mode so Different

    Geiger-mode sensors sample the same spot on the ground multiple times

  • | 9 Airborne Geiger Mode LiDAR Technology to Connect, Inform and Protect TM

    GmAPD Multi-Look/Multi-Pulse Collection

    Multi-look approach

    4096 measurements per laser flash

    50,000 flashes per second

    Approx= 205 million elevation

    measurement per second

    Every spot illuminated 100s of times

    The dozens of photon detections are

    processed to determine the real objects

    Programmable Forward/Sidelap

  • | 10 Airborne Geiger Mode LiDAR Technology to Connect, Inform and Protect TM

    Improved Accuracy Results

    Required input:

    Utilize high grade INS/GPS

    Utilize horizontal and vertical GPS ground control objects

    Opposing 50% overlap sorties create four looks

    Process:

    Perform horizontal/vertical bundle adjustment via GPS tie points

    Perform auto tie point registration from multiple look angles

    True photogrammetric bundle adjustment provides higher accuracy

    Aggregating multi-look data requires highly accurate alignment

  • | 11 Airborne Geiger Mode LiDAR Technology to Connect, Inform and Protect TM

    SBET refined to produce final Aggregate Points

    Multi-Swath Alignment via Sensor Based

    3D Photogrammetric Bundle Adjustment Enables Rigorous

    Accuracy Statements per Point

    Sensor-based adjustment enables per point accuracy statements
