Uncertainty of stream networks derived from elevation data

Short title:  streams_error

A Sextante implementation of these algorithms called FlowTools can be obtained here (contributed by Daniel Nüst). The project report can be downloaded as a PDF. You can access the Eclipse project “flowTools” in the following public Subversion repository:


You can also download an initial version (might be outdated!) of the project folder as a zip file (12).
