Breaklines are very useful for describing a terrain - for example to build an exact TIN.
My question is, how to extract these breaklines from a given DEM?
I calculated the curvature (vertical) - raster (using arcgis 10), where you can see the breaklines (min/max-curvature), but I did not figure out how to extract them to get polylines in the end.
What is the workflow to get these breaklines from a DEM?
Does anyone have an idea of a workflow, or a "tool", or skript, which can help?
I think I am not the first/last man who wants to perform this task:)
...in the meanwhile i have found a paper on this topic that seems to be a good solution, but the big question remains: how to reduce that to practice?
Or has anyone a different (easier?) approach with some software?
