“Decision-Ready”, High Accuracy Maps While Still-In-The-Air, As They Are Collected
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
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
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
Trimble Digital Sensor System (DSS) 500 with In-FlightOrthoTM
Trimble DSS 500 Industry’s First Aerial Imaging Solution with “In-Air” Orthophoto Production
Trimble DSS 500Much more than “just a camera” • DSS is a directly-georeferenced, medium-format imaging solution • DSS includes a completely integrated, ready-to-use workflowwith 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
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
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
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
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
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
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
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
Advantages • Low cost to operate • 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
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
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
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)
