How to quantitatively evaluate the quality of the watershed delineation stream line results
How can we quantitatively describe the quality of watershed delineation?
What metrics can I use to compare the stream line differences between a few delineations using different DEMs with different resolutions?
Ideally, if the DEM is fine enough, there should one of the metrics indicating how much they overlap with actual stream line.
My current idea is to calculate the total area of two polylines. The closer they are, the smaller the area should be.
Any useful thought will be appreciated.
