  3. LIDAR workflowshigh speed point cloud generation

  4. Sample LIDAR-derived DEM data productssafety • Disaster prevention / disaster monitoring • Forest fire fuels assessment

  5. Sample LIDAR-derived DEM data productssecurity • Defense • Supply route monitoring • Spot reconnaissance • Base mapping • Homeland security • Border monitoring • Urban event risk assessment • Law enforcement • Covert activity detection

  6. Sample LIDAR-derived DEM data productsenvironment • Coastal survey • Watershed management • Flood zones • Erosion • Forest management • Tree health • Biometric data • Forest inventory • Development impact / change detection Image courtesy of Watershed Sciences

  7. Sample LIDAR-derived DEM data productsfused data for multiple applications • Typical sensors co-collecting with ALS DEM data • Medium-format RGB • Medium-format CIR • Thermal imagery • Hyperspectral imagery • Auxiliary sensors collect: • Additional spectral regions • High definition planimetric data

  8. Future development in LIDAR-derived DEM workflowsmarket requirements, paths for 3rd-party developers • Speed – but can be overcome with more CPUs • Black box – minimizing human interaction, especially during the filtering and editing stages; possible impact of Full Waveform Digitizing (FWD) LIDAR data on accuracy and ability to filter data • Multi-sensor automation - easier fusion from dissimilar sensors – airborne LIDAR + terrestrial LIDAR, LIDAR + airborne (Vis or NIR) imager, LIDAR + thermal imagery • Auto QC – automating the quantitative measurement of output data quality

  9. What’s newadditional milestones since ASPRS annual meeting Image courtesy of North West Geomatics • Huge projects being undertaken w/ MPiA systems (Example – NWG has collected 315,000 km², 835 aircraft hours, 1 point / m², 0 sensor problems to date on 750,000 km² collection) • Number of new system deliveries/demos for high altitude use @ 4500 m – 6000 m AGL • Hexagon acquires NovAtel • Participation in large-scale defense exercises • Customer support staff increased to 30 staff 4500 m AGL, MPiA, 66º FOV, 1.5 m avg. post spcng
