La génération de points par lot ne fonctionne pas

<\/HEAD>

J'essaie de cartographier un bassin versant pour une zone et j'ai presque terminé, mais le bouton BPG pour ArcHydro (le petit X jaune) ne fonctionne pas correctement. Apparemment, lorsque je l'utilise et que je clique sur un emplacement, une fenêtre est censée apparaître pour créer la couche de points par lot où je suis censé la nommer "BatchPoint", suivie d'une seconde fenêtre où je nomme le point réel et mets une description.  Mais actuellement, lorsque je clique sur un emplacement, la première fenêtre est complètement ignorée et on passe directement à la fenêtre de nom/description.  La couche "BatchPoint" ne semble pas exister du tout car je ne la vois pas comme un fichier sélectionnable, ni ailleurs. Remplir la fenêtre de nom/description ne semble absolument rien faire. Y a-t-il un problème avec mon installation ou un autre souci que je ne connais pas ?<\/P>

Merci d'avance.<\/SPAN><\/P><\/BODY><\/HTML>

Arc Hydro uses "target locations". These are locations where the raster and the vector data is written when it is created. This keeps you from having to create folders and a geodatabase and also telling Arc Hydro where to put/get data. The BatchPoint features should be written to the geodatabase and dataset for the vector data. If these targets are not set correctly, Arc Hydro will possibly put the data in the wrong place and even overwrite a previous project's data!

Below is a copy and paste from a doc I wrote for myself a while back and just updated slightly to help keep target locations straight.

Hope this helps:

If you are starting a new mxd and adding the dem and vector layers to start your Arc Hydro project, Arc Hydro will set the Target Locations automatically and you don't have to mess with them.

If you want to check them they should follow the pattern below:

Given:

mxd path = C:\MyProjectFolder\

mxd name = MyProject.mxd

data frame name = MyDataFrame (The default is "Layers" in all mxds. If you change the data frame name BEFORE running any Arc Hydro function or else you will need to reset the target locations.)

You can check the target locations using the Arc Hydro tool bar menu:

ApUtilities>Set Target Locations>HydroConfig

• Map Level     Map Name:      MyDataFrame

     Raster target location path:      C:\MyProjectFolder\

     Vector target location:              C:\MyProjectFolder\MyProject.gdb

With these settings, the raster data is stored in a folder:  C:\MyProjectFolder\MyDataFrame and the vector data is stored in a geodatabase and feature dataset: C:\MyProjectFolder\MyProject.gdb\MyDataFrame

When you look under ApUtilities>Set Target Locations>HydroConfig should be the target location setup.

If you save the mxd and data to another location, you will need to make sure the target locations are corrected or else the results of the Arc Hydro functions will end up in the old target! This will be confusing for Arc Hydro and may lead to other errors.

There is a utility the resets the Target Locations. This is really handy. If you move the mxd and data, you can reset the target locations using the following utility:  ApUtilities>Additional Utilities>Reset Target Locations
