1. ASPRS 2008 Airborne Digital Mapping Camera Systems: A Manufacturers’ Perspective Ruedi Wagner, ADS Product Manager Portland, 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. Consistent Technical Performance
Resolution/GSD [IN ALL BANDS!!!!!]
Geometric Stability
= Geometric Accuracy [SUBPIXEL] + =
Telecentric Lens
Equal Resolution
Co-registered in all
bands
Tetrachroid
NO PAN-SHARPENING

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

6. 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)
Flexibility in SH51 & 52

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

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

9. Data Processing Efficiency Digital workflow = analog workflow
