Bewertung Depression

Question

<\/HEAD>Ich habe die Depression Evaluation bereits 8 Mal ohne Fehler durchgeführt, aber jetzt erhalte ich bei meinem 9. Versuch immer denselben Fehler. (siehe Anhang). Ich habe nichts anders gemacht als bei den vorherigen 8 Durchläufen. Ich habe die Hintergrund-Geoverarbeitung deaktiviert und nach den ersten paar Fehlern alles aus meinem Temp-Ordner gelöscht, ArcMap neu gestartet, die Shapefiles gelöscht, die während des Fehlers erstellt wurden, um Überschreibungsfehler zu vermeiden, aber trotzdem tritt jedes Mal derselbe Fehler auf! Wenn jemand Vorschläge hat, wäre ich sehr dankbar!! Vielen Dank!<\/P> <\/P><\/BODY><\/HTML>

In noticed when looking at the posted screenshot that several of the paths used appear to contain restricted characters.  Specifically, there seems to be periods in folder names.  If that is the case, try renaming them to underscores or otherwise eliminate them, as restricted characters will often trip many types of raster processing.

Also, it is recommended if possible, keep the path as short as feasible and avoid long file and folder names.  Even though in theory one could have long paths, in reality raster processes can choke or throw errors if long paths are used.  Yet the same process will work without issues if the path is shortened.  For example, put the data in something really short like C:\Test\Water.

Thanks, Ashley! I finally figured it out. I found that my DEM was way too large (an entire county) and my graphics/video card on my laptop couldn't handle the geoprocessing. I created a subset, converted it from floating point to an integer, converted the raster to GRID format, and raster calculated all NoData values to 0. I did a restart, opened a new map document on a different (more robust) desktop, and it worked!

Hi Laura...I ended up creating a new map document.  I was on my 7th or 8th round of Depression Evaluation so I created my new map document with those shapfiles and ran DE exactly how I was in the old map document and it worked fine. Hope this will help you out!
