Creating a line between points...

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, (
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?

Any advice would be much appreciated.

You may want to take a look at the Hydrology tools of Spatial Analyst extension.
