  2. ALS50-II Airborne LIDAR Scannercontinued innovation, expanded performance • Breakthrough system design allows 150 kHz pulse rate with no loss in accuracy • Multiple Pulse in Air (MPiA) technology • carries 150 kHz performance to 1569 m AGL • 2x pulse rate improvement over conventional systems altitudes above 1400 m AGL • Improved 90 Hz maximum scan rate • Fully integrated FCMS flight navigation with airborne-certified displays • Compact electronics • Simple 3rd-party sensor integration using embedded IPAS10 GNSS/IMU subsystem

  3. ALS Corridor Mapperresponding to emerging markets • Uses key ALS technologies • 1000 m AGL maximum flying height • High accuracy and high point density, even at maximum flying height • Corridor or “large-map-scale” applications • Lower price point

  4. Purpose-designed airborne camera RGB or CIR operation 35, 60 and 100 mm lenses Fast 2.02 second frame interval User-replaceable 1/4000-sec shutter RCD105 Digital Frame Camera introduction39 MP: fast, flexible, plug-and-play with ALS50-II

  5. Significant milestonestechnology put to work Image courtesy of North West Geomatics • MPiA is now a mainstream technology • Huge projects being undertaken w/ MPiA systems (Example – NWG has collected 315,000 km², 835 aircraft hours, 1 point / m², 750,000 km² collection) • Number of new system deliveries/demos for high altitude use @ 4500 m – 6000 m AGL 4500 m AGL, MPiA, 66º FOV, 1.5 m avg. post spcng

  6. RCD105 Digital Frame Camera for ALS50-IIrugged design for precise imagery

  7. LIDAR trendswhere is LIDAR in the “adoption curve”? • Market is still growing • ~249 LIDAR systems sold (total market) since mid 1990s • Rate at which LIDAR systems are entering the market is doubling every 3-4 years • 48 LIDAR systems entered the market in 2007

  8. LIDAR trendswhat are the application market trends? • Increased interest in infrastructure measurements • Railways • Roads • Power lines • Pipelines • National forest inventory • Biomass • Carbon uptake

  9. Point density  laser pulse rates doubling every ~2 years Point accuracy  customers pushing the limits of technology, but limited by GNSS accuracy Availability of high-accuracy position data increasing with introduction of GPS + GLONASS Increasing use of “fitting” software (e.g., TerraMatch) Regulatory issues import/export getting easier to deal with due to wider IMU availability Use of auxiliary sensors  over 50% of LIDAR systems have integrated imaging sensors Medium format Large format Multispectral Thermal Processing speed  increasing number of 3rd-party workflow suppliers LIDAR trendswhat are the technology trends?

  10. Outlook and summary • Demand for data is still increasing • LIDAR and medium format camera systems continue to show rapid increases in performance • Point density and point acquisition speed (i.e., pulse rate) continue to dominate in the field of new features the market is demanding • New processing architectures are making inroads, but no obvious replacements for current processing methodologies
