Évaluation de la Dépression

Question

<\/HEAD>J'ai exécuté l'Évaluation de la Dépression 8 fois auparavant sans erreurs, mais maintenant à ma 9e tentative, je reçois toujours la même erreur. (voir pièce jointe). Je n'ai rien changé par rapport aux 8 exécutions précédentes. J'ai désactivé le géotraitement en arrière-plan et après les premières erreurs, j'ai supprimé tout le contenu de mon dossier temporaire, redémarré ArcMap, supprimé les shapefiles créés lors de l'erreur pour éviter toute erreur d'écrasement, mais l'erreur persiste à chaque fois ! Si quelqu'un a des suggestions, elles seraient grandement appréciées !! Merci beaucoup !<\/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!
