Calculating the direction of streams in a polyline shapefile

Discussion created by christos on May 9, 2012
Hi everybody,

I have created a polyline shapefile that contains data about the streams in a hydrologic basin (such as stream order etc). The tools that I used from Spatial Analyst Tools > Hydrology in order to produce the resulting polyline shapefile was: DEM> Fill > Flow Direction > Watershed> Stream Order > Stream To Feature. My question is how can I calculate the direction for each line in the resulting Stream To Feature polyline shapefile?
I would apprecite it if someone could provide me with an answer.

Thank you
