nelze resetovat BatchPoint

JingTao

<\/HEAD>Omlouvám se, moje předchozí zpráva níže potřebuje upřesnění: jak vlastně mohu vytvořit druhou vrstvu batchpoint, která nemá nic společného s existující a má jiný název? <\/SPAN>
Používám ArcHydro 2.0 a snažím se resetovat tag Batchpoint. Zkoušel jsem všechny možnosti uvedené v předchozí verzi návodu\/tutoriálu - odstranění existující vrstvy Batchpoint z Obsahu tabulky, výběr Watershed Processing\/Data Management\/nastavit BatchPoint na Null, nebo výběr ApUtilities\/XML Manager\/HydroConfig\/TemplateView\/.... Žádná z těchto možností nefunguje. Ve chvíli, kdy kliknu na tlačítko pro generování batchpoint a kliknu kdekoli na mapě, okamžitě se v Obsahu tabulky objeví existující vrstva BatchPoint a nedá mi to šanci vytvořit novou třídu prvků Batchpoint. Máte nějaký návrh? Předem děkuji!<\/SPAN><\/BODY><\/HTML>

My experience with Arc Hydro is that it uses default names as much as it can. For example, the "agreestream" layer or "rawdem" are defaults. If they exist in the mxd, they will be "grabbed" when a Arc Hydro process is started.

You can use another layer for the BatchPoints. If, however, you are trying to use the Batch Point Generation tool, it will create the layer with the name "BatchPoint" since that is the default name.  One way around this is to copy the BatchPoint layer to another layer. This will have all the right fields for Arc Hydro to use. Then, delete the BatchPoints layer and start again. You will then have two layers with batch points, but different names. You should be able to use either one in the delineation processes.

You can add points to these without having to use the Batch Point Generation tool. You just have to populate the fields manually, which is easy.

I have often saved the BatchPoint layer from the geodatabase to a normal feature class so that I can start my Arc Hydro process over by deleting the geodatabase and raster folder altogether. It gives me a fresh start on an Arc Hydro project w/out loosing the work I went through in setting the batch points. After I create a "dummy" batch point using the Batch Point Generation tool, I just delete that point and copy the saved points to the new BatchPoint layer.

HEC-GeoHMS has a tool for importing batch points. It can be used without starting a GeoHMS project. It has come in handy at times.

Hope this helps.
