2 ALS50-II Airborne LIDAR Scanner continued 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 3 rd -party sensor integration using embedded IPAS10 GNSS/IMU subsystem

3 ALS Corridor Mapper responding 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 RCD105 Digital Frame Camera introduction 39 MP: fast, flexible, plug-and-play with ALS50-II 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

5 Significant milestones technology put to work 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 4500 m – 6000 m AGL 4500 m AGL, MPiA, 66º FOV, 1.5 m avg. post spcng Image courtesy of North West Geomatics

7 LIDAR trends where 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 trends what are the application market trends? Increased interest in infrastructure measurements  Railways  Roads  Power lines  Pipelines National forest inventory  Biomass  Carbon uptake

9 LIDAR trends what are the technology trends? 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 3 rd -party workflow suppliers

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
