1 “Decision-Ready”, High Accuracy Maps While Still-In-The-Air, As They Are Collected

2 Ultra-Fast Mapping: Why? When?
Natural disasters require immediate response to save lives and property to survey damage to identify open access routes Security emergencies Decision ready imagery needed INSTANTLY to plan and execute response

3 Challenges Large aircraft (or satellites) must fly high to capture images, the cloud deck often impedes image capture Ortho-processing many small images using traditional Aerial Triangulation (AT) process is time consuming AT requires good quality ground control information, which is very difficult to collect in unstable post-crisis areas Large format cameras can’t efficiently collect data of small/irregular areas

4 Solution Smaller aircraft and medium-format cameras are ideal
Direct Georeferencing In-FlightOrtho software produces full resolution orthorectified imagery in the aircraft as it is captured. Images are automatically developed, corrected and orthorectified

5 Trimble Digital Sensor System (DSS) 500 with In-FlightOrthoTM

6 Trimble DSS 500 Industry’s First Aerial Imaging Solution with “In-Air” Orthophoto Production

7 Trimble DSS 500 Much more than “just a camera”
DSS is a directly-georeferenced, medium-format imaging solution DSS includes a completely integrated, ready-to-use workflow with IMU, flight management, metric imaging camera, software, and support/maintenance for all components Every DSS includes In-Flight Ortho and RapidOrtho for ultra fast orthophoto production

8 DSS 500: Dramatically New The DSS 500 with In-FlightOrtho is the next generation of DSS solutions, comprised of: All-new compact camera system with embedded computer, solid-state drives, Applanix POSTrack V6 7” Pilot smart display 8.9” Operator tablet (not required for pilot only operation) Azimuth mount or optional 3-axis SSM 270 mount Various camera and lens options, 39 MP/80 MP RGB or CIR or NIR “In-Air” image production

9 In-FlightOrtho™: Only with DSS
Every DSS has what no other system has – the ability to produce directly georeferenced orthos in real-time, in the air. Real-time image and ortho thumbnail display

10 In-FlightOrtho™ (comes included on all systems)
Real-time image & ortho thumbnail display Instantly detect issues with imagery and georeferencing: “Air-to-ground QC” No special computer HW required; off-the-shelf laptop with SSD and Ethernet cable Absolute accuracy limited by DEM accuracy and source of GNSS corrections Sub-meter accuracy possible with Omnistar XP

11 Why DSS 500? Every DSS Includes In-FlightOrtho and RapidOrtho
Ideal for rapid, high-accuracy mapping Direct georeferencing computes position of points on ground without GCP – no Aerial Triangulation (AT) required Mapping grade camera calibrated, stable over time Process certified by the USGS

12 Why DSS 500? continued Flexibility of variable focal lengths
Radiometric accuracy Complete turnkey solution including: all hardware and software Workflow Installation Training warranty and support

13 Direct Georeferencing
Measures position and orientation using Navigation Sensors Computes position of points on ground without needing GCPs Ideal for medium-format digital camera where traditional AT can often be difficult & costly due to large number of images & GCPs required

14 Direct Georeferencing continued
Orthophoto production can be completed in hours; not months / weeks / days Saves cost and reduces the risk of placing personnel in dangerous environments to collect GCPs With In-FlightOrtho direct georeferencing can be obtained on the fly

15 Advantages Low cost to operate Platform for future business growth
state-of-the-art computer hardware is extremely compact, low-power can be easily deployed in small, low-cost-to-operate aircraft for very cost-effective mapping proven pilot-only operation, reducing personnel and fuel costs Platform for future business growth Designed to scale to support future OTS computing hardware, reducing your future upgrade costs Supports other sensors, so you can grow as your business grows

16 Advantages Continued Directly Georeferenced Imagery
DSS is designed and built around the use of Applanix POS AV Direct Georeferencing for maximum productivity and accuracy Super Efficient Flight Management System With an embedded POSTrack flight management system with full DEM support, the DSS is capable of taking each and every image at exactly the right location and overlap

17 Advantages Continued “Air-to-Ground” Quality Control
The ultimate in-field Quality Control through In-FlightOrtho capability Full-res orthophotos are produced in real-time immediately upon image capture using the GNSS-Inertial solution and onboard DEM The pilot / operator can see at a glance how things look and fit together “on-the-ground”, immediately verify the quality of the imagery, GNSS data, Inertial data and camera interior orientation. If a problem is spotted the mission can be immediately aborted, or images re-flown. Benefit: massive potential cost savings in flight & ground costs

18 Who uses the DSS? Government mapping agencies
Civil and defense applications Small and medium-sized mapping companies Corridors, small / irregular collects, low-altitude (under cloud) Combined with LIDAR Smaller aircraft = dramatically lower operating costs Larger mapping companies Same small / irregular projects, seen as complementary to large-format camera systems (reduces cost on small projects)
