  1. ASPRS 2008Airborne Digital Mapping Camera Systems: A Manufacturers’ PerspectiveRuedi Wagner, ADS Product ManagerPortland, 1st May 2008

  2. „Perspective“ • „The faculty of seeing all the relevant data in a meaningful relationship.“

  3. What is „relevant“ to the Customer in aerial digital mapping? • Consistent Technical Performance? • Data Acquisition Efficiency? • Data Processing Efficiency?

  4. + = Equal Resolution Co-registered in all bands + = Telecentric Lens Tetrachroid Consistent Technical Performance • Resolution/GSD [IN ALL BANDS!!!!!] • Geometric Stability • = Geometric Accuracy [SUBPIXEL] NO PAN-SHARPENING

  5. ADS40 2nd Generation Highest Quality at Engineering Accuracy [5cm GSD image]

  6. Flexibility in SH51 & 52 Consistent Technical Performance • Radiometric Calibration/Performance • „For automated classification, the ADS40 SH52 shows by far the best accuracy.“ [Kass Green, ASPRS 2008] • Stereo Capability in all five bands (SH52)

  7. Radiometrically Calibrated Image Data in Full StereoSample images RGB & NIR (Wörthsee)

  8. 36,000 lx 72,000 lx 18,000 lx Data Acquisition EfficiencyExpanding the Operational Envelope 18,000 lx Target: Image data with full dynamic range.

  9. Data Processing EfficiencyDigital workflow = analog workflow Total time User action time 2,400 km2, 20cm GSD 30 lines, each 40 km, 3 Pan and 4MS Approximately 8h flight at 130knots Flight Workstations single eight 230 GB ADS data format = 940 GB image data Download 0.5 h 4 h 4 h Trajectory calculation geo-referencing of L0 images Geo- referencing 2 h 2 h 2 h 2 h 1.5 h 0.5 h Automatic Point Measurement Bundle Adjustment Aerial triangulation 8 h 12 h 3 h 12 h 0.5 h 5 h RGB or FCIR 2,400 km2 (927 sq.mi) Ortho photo 44 h 6 h 1.5 h 29 h 72 h 9.5 h Due to image strips slightly faster than in traditional workflow Feature extraction Similar to traditional workflow Fly-through

  10. √ √ √ Conclusion Is this meaningful to you? Is this a perspective you can share with us? • Technical Performance? • Data Acquisition Efficiency? • Data Processing Efficiency? • = Bringing Value to the Customer
