After attempting to create stream order attributes via Lidar processing using the Hydrology Toolbox, I have circled back to this. Due to low coastal elevations and landuse changes, the lidar output isn't lining up with the stream polyline data that I already have.
I have a stream polyline, but I need stream order attributes. I have lidar, which I have used to create flow direction and flow accumulation grids. I attempted to use the "Create Drainage Line Structures" tool, however I received an error due to missing HydroIDs. I used the Assign HydroID tool within the Attribute Toolbox and tried again. It is still failing to execute. Am I missing something? Should I be using the lidar data as the raw DEM instead of the flow direction or flow accumulation grids? Do I need to specify file type?
If anyone has any experience with identifying stream order using known streams and lidar, I would really appreciate the help.
Thanks,
Nicole
