ArcHydro herkent workspace of doel locaties niet in Python?

<\/HEAD>

Ik ben momenteel bezig met het herschrijven van de volgende Python Module:<\/P>

<\/P>

• ArcHydro Pre-processing<\/A> <\/LI><\/UL>

  <\/P>

  Ik realiseerde me net dat ArcHydro de arcpy.env.workspace of de ArcHydroTools.SetTargetLocations("HydroConfig", "Layers", "RasterWorkspace", "VectorWorkspace") niet herkent<\/P>

I don't know if this will fix your problem, but I was having a similar issue (except with vector location instead of raster location) with ThinCrossSection tool even though I set the arcpy enviroment and ArcHydro's target locations.

The issue seems to be that you need a full path to a feature instead of just the name:

<SPAN class="comment token"># This did not work for me</SPAN>
ArcHydroTools<SPAN class="punctuation token">.</SPAN>ThinCrossSection<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"TEMP"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"MaxNumberOfVertices"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="number token">500</SPAN><SPAN class="punctuation token">,</SPAN> output<SPAN class="punctuation token">,</SPAN> report<SPAN class="punctuation token">)</SPAN>

<SPAN class="comment token"># This did</SPAN>
output <SPAN class="operator token">=</SPAN> gdb_path <SPAN class="operator token">+</SPAN> <SPAN class="string token">'\\'</SPAN> <SPAN class="operator token">+</SPAN> output
report <SPAN class="operator token">=</SPAN> gdb_path <SPAN class="operator token">+</SPAN> <SPAN class="string token">'\\'</SPAN> <SPAN class="operator token">+</SPAN> report
ArcHydroTools<SPAN class="punctuation token">.</SPAN>ThinCrossSection<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"TEMP"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"MaxNumberOfVertices"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="number token">500</SPAN><SPAN class="punctuation token">,</SPAN> output<SPAN class="punctuation token">,</SPAN> report<SPAN class="punctuation token">)</SPAN>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

And with this, I just had to set the arcpy workspace - I don't need to call SetTargetLocations from ArcHydro.

So specifically for yours, replacing 'fil' in the FillSinks call with the full path to 'fil' might work
