9. 9 Feature Identification - Pfafstetter coding From the Ocean - down to the lowest level.

10. 10 Example Elbe on German Czech Border North Sea Pfafstetter Code = 5 Elbe one of the 4 biggest seaoutlets in the North Sea Code = {2,4,6,8} -> choose 4 Final code of the segment- lowest level catchment 5927 5.4. 5.9.2.7 Second Large Seaoutlet on a Sea not too far from the Ocean in the longest stretch of an intermediate branch Feature Identification

13. 13 Final Comments 1.SRTM will be followed by 30 meter resolution models 2.Image2000 Like datasets will be available for the whole planet 3.Automatic water quality control methods will grow exponentially 4.Weather-forecast, drought and flooding hazards applications will become an internet commodity 5.Data quality and availability is not a problem 6.Processing power and storage is not a problem 7.Metadata will be generated automatically 8.Automatic coding is not a problem, only a choice and a decision 9.We have problems in keeping up with the pace to benefit from useful options.
