stream extraction

Discussion created by MalgosiaMendela on Mar 27, 2013
Hello,
could you please help me to solve the following problem:

I need to create automatically a stream using a raster as input data (Ob17_1).
I have applied Reclass (3D Analyst Tools-Raster Reclass) and Thin (Spatial Analyst Tools- Generalization) tools, but these could not (are not sufficient) generate appropriate (such as real ones) bends (bends.bmp).

Do you know whether it is possible to add some extra points belonging to bends and then automatically generate bends passing exactly through these trouble spots (extra points)?

Thank you,
Malgosia
