Tool 04a - Stream Network Point Issue #22

Closed fluvialjack closed 1 year ago

fluvialjack commented 1 year ago

Hi there,

Prewarning that I'm not proficient in python or R to any standard so I apologise in advance if this is a simple user error.

Upon attempting to run 04a I am faced with this error:

Workspace: D:\ENG_Engeny\Unlicensed Drain Standard\Arc_Work\Engeny_Unlicensed_Drains_Guidance\Model_Testing.gdb Stream Network: streamnetwork1 Flow Accumulation Model: flow_accumulation_d8 Digital Elevation Model: Filled_DEM Stream network route created Traceback (most recent call last): File "D:\ENG_Engeny\Unlicensed Drain Standard\Arc_Work\Toolbox\FluvialGeomorph-toolbox-master\tools_04a_StreamNetworkPoints.py", line 164, in arcpy.Delete_management(in_data = stream_network_route)

Failed script 04a - Stream Network Points... Failed to execute (StreamNetworkPoints).

Any help would be appreciated.

Cheers, Jack

I have found the issue here. The "Reach Name" attribute is being populated as . Assigning a unique value to the reach name seems to fix the problem. Not sure if this will allow the tool to work for ongoing steps but it does allow Tool 4a to return the stream network points. Cheers, Jack
