BatchPoint をリセットできません

JingTao

<\/HEAD>申し訳ありませんが、前回のメッセージにはいくつか明確にする必要がありました。基本的に、既存のものとは関係なく、異なる名前を持つ2番目の batchpoint レイヤーをどのように作成できますか？<\/SPAN>
私は ArcHydro 2.0 を使用しており、タグ Batchpoint をリセットしようとしています。以前のバージョンのガイダンス／チュートリアルドキュメントに記載されているすべてのオプションを試しました - 目次から既存の Batchpoint レイヤーを削除する、Watershed Processing／Data Management／set BatchPoint to Null を選択する、または ApUtilities／XML Manager／HydroConfig／TemplateView／... を選択するなど。しかし、これらのオプションはどれも機能しないようです。batchpoint 生成ボタンをクリックしてマップ上のどこかをクリックすると、既存のレイヤー BatchPoint が瞬時に目次に表示され、新しい Batchpoint フィーチャクラスを作成する機会が与えられません。何か提案はありますか？事前にありがとうございます！<\/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.
