3 Geiger-Mode LiDAR World leader in next generation Geiger LiDAR technology. Advantages Wide Area Mapping Greater Point Density Higher Cost Effectiveness Better Precision/Accuracy Airborne Geiger Mode LiDAR 3

4 Collection Simulation Comparison (8ppm) Higher Faster Greater Resolution Airborne Geiger Mode LiDAR 4

5 Collection Metrics at 8ppm Superior Performance Linear LiDAR Geiger LiDAR Density (points per meter) 8 8 Instantaneous Coverage Rate (mi2/hr) 50 17x 850 RMSEz (cm) Altitude (AGL ft) 3,200 27,000 Swath Width (ft) 3,300 16,000 Ground Speed (kts) Efficiency gains keep costs down at higher collection densities Airborne Geiger Mode LiDAR 5

6 Collection Cost Higher Efficiencies at Higher Resolutions Linear Systems Geiger-mode Collection Density (points per square meter) Higher the resolution greater the payback Airborne Geiger Mode LiDAR 6

7 Solution: Multi-Look and Oversampling Airborne Geiger Mode LiDAR 7

8 What makes Geiger Mode so Different Geiger-mode sensors sample the same spot on the ground multiple times Airborne Geiger Mode LiDAR 8

9 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 100 s of times The dozens of photon detections are processed to determine the real objects Programmable Forward/Sidelap Airborne Geiger Mode LiDAR 9

10 Improved Accuracy Results Aggregating multi-look data requires highly accurate alignment 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 Airborne Geiger Mode LiDAR 10

11 SBET refined to produce final Aggregate Points Multi-Swath Alignment via Sensor Based 3D Photogrammetric Bundle Adjustment Enables Rigorous Accuracy Statements per Point Pre > Post adjustment Sensor-based adjustment enables per point accuracy statements Airborne Geiger Mode LiDAR 11

12 Benefits of Geiger-mode LiDAR Dramatically improves speed of collection Higher density (resolution) at lower cost Improves foliage penetration (Better terrain information) Multi-look reduces shadows and voids (Higher quality) Robust bundle adjustment (Higher accuracy) Enterprise production (Improved Delivery/Schedule) Large-area, high-density collection leads to new adopters and opportunities Airborne Geiger Mode LiDAR 12

13 8 points per meter: Higher Point Density enables accurate decisions 8 ppm Profile Actual Survey Elevations Technology to Connect, Inform harris.com and Protect Nearly mirrors existing high precision survey data. Airborne Geiger Mode LiDAR 13

14 Why do higher densities matter? Improves foliage penetration to better sample 8 pts/m2 2 pts/m 2 8 pts/m 2 20 pts/m 2 Infrastructure details better defined bare earth 20 pts/m 2 2 pts/m 2 8 pts/m 2 Improves accuracy and enables a high level of automation Airborne Geiger Mode LiDAR 14
