Het lukt me niet om Langste stroompad voor stroomgebieden in ArcHydro succesvol te laten werken, omdat ik steeds fouten 010429 en 010067 krijg wanneer ik het uitvoer. Weet iemand hoe dit voorkomen kan worden? Ik gebruik ArcGIS 10.6.1 op Windows 10 en de nieuwste versie van ArcHydro (10.6.0.13). Hoewel ik nieuw ben met het gebruik van ArcHydro, zijn er niet veel invoeropties voor deze tool, dus ik begrijp niet wat ik verkeerd zou kunnen doen. Ik heb enkele van de suggesties hier<\/A>, geprobeerd, zonder resultaat. Bijgevoegd is een screenshot van het foutbericht dat ik ontvang evenals de stroomgebieden en stroomlijnen die ik kon afbakenen voor het project waaraan ik momenteel werk.<\/P><\/BODY><\/HTML>
I see that the Python tool for LFP for Adjoint Catchments also requires LFP for Catchments as input. Was this with a different version? Has the memory leak been addressed? I'm still getting an error like this.
Were you able to solve this? I am getting the same error message repeatedly. Cannot get past this step.
Thanks
That doesn't work either. Longest Flow Path for Adjoint Catchments requires the output from Longest
Flow Path for Catchments, as seen below.
If I try to run Longest Flow Path for for Adjoint Catchments using the output I got from Longest Flow Path for Catchments or Drainage Lines, an error message pops up: "No corresponding flowpath found for catchments!". Is there a workaround I should be aware of to avoid this?
Try to use the Python version of the Longest Flow Path for Adjoint Catchments tool under the Arc Hydro Tools Python toolbox. It skips the Longest Flow Path for Catchments step which is problematic for large rasters (memory leak). To support LFP for Watershed, you do not need the LFP for Catchments, only the LFP for Adjoint Catchments.

I went through all of those steps once again in order and still got stuck on Longest Flow Path for Catchments. In the image I posted I had the adjoint catchments turned by accident, which is why it looked like there were two centroids per catchment.
Looking at your watershed boundaries and points, it seems odd that there are two points in each watershed (polygon) as well as two drainage lines (blue polylines). If the points are centroids, then there is something wrong. The "two points inside each polygon" is so consistent, it makes me think that maybe you change the number of cells in the stream definition an didn't rerun some other part of the Basic Dendritic Terrain Processing functions
If the polygons are the catchment layer, then I'd check to make sure everything is correct at that step.
Flying in the blind here since I don't know everything about your project, but if you redo any step before the step you are one, you have to redo all the steps in between. There's a good chance you didn't do this, but maybe there is something is a process before the longest flow path routine that is not finishing.
I've inserted a screen capture and highlighted just the steps I use. They have to be done in order and if you re-do any step, you must redo all the following steps.
Heading out of town with limited ability to follow this. Hope you figure it out!
