I'm trying to create a polyline of streams/river as derived from a DEM raster at 50m x 50m cell resolution.
I've managed to get as far as creating a point layer showing a point for each cell, but can't jump from point to polyline.
I've tried the Points to Line tool, (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00170000003s000000) but it strings together the points in ID order and doesn't allow for you to set a 50m radius catchment for the nearest cell point, that would no doubt allow me to recreate the river as a polyline using (if you like) Toblers first law. 🙂
Maybe it can only be done using code, but I'm very poor on this side of things. Does anyone have any suggestions?
