12. Geometric Quality

13. Improvements CCM2
Systematic generation of water bodies and flow on the full Pan-European scale (including Turkey and up to Ural)
Based on 90m digital terrain model (~10 times as detailed as before)
Landsat 7 Water detection for rivers in plains ( m resolution)
Full Strahler and Pfafstetter coding
Fully space born

14. Project Progress + SRTM filling and projecting ready for whole area
+ SRTM integration with Scandinavia 100 meter
+ Landsat 7 ready for EU 27 CH, West Balkan
- Landsat 7 to be added for the East, Norway and Turkey
+ Integration automated
- update thresholds
- run CCM model per Seaoutlet
- integrate and update database
+ generate Strahler and Pfafstetter

24. Conclusions Outlook to GPS precision One method up to 60 degrees
From scale to resolution
Pfafstetter and Strahler give many options visualization and grouping
Just the beginning…
