Ultra-Fast Mapping: Why? When?
2
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
![Page 3: Decision-Ready, High Accuracy Maps While Still-In-The-Air, As They Are Collected 1](https://reader035.vdocuments.us/reader035/viewer/2022070306/5517676a55034645368b4941/html5/thumbnails/3.jpg)
Challenges
3
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
![Page 4: Decision-Ready, High Accuracy Maps While Still-In-The-Air, As They Are Collected 1](https://reader035.vdocuments.us/reader035/viewer/2022070306/5517676a55034645368b4941/html5/thumbnails/4.jpg)
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

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)
