incapaz de redefinir BatchPoint

JingTao

<\/HEAD>Desculpe, minha mensagem anterior abaixo precisa de alguns esclarecimentos: basicamente, como posso criar uma segunda camada batchpoint que não tenha nada a ver com a existente e tenha um nome diferente?<\/SPAN>
Estou usando ArcHydro 2.0 e tentando redefinir a tag Batchpoint. Tentei todas as opções listadas na versão anterior do documento de orientação\/tutorial - remover a camada Batchpoint existente da Tabela de Conteúdos, selecionar Watershed Processing\/Data Management\/set BatchPoint to Null, ou selecionar ApUtilities\/XML Manager\/HydroConfig\/TemplateView\/.... Nenhuma dessas opções parece funcionar. No momento em que clico no botão para geração de batchpoint e clico em qualquer lugar no mapa, a camada existente BatchPoint aparece instantaneamente na Tabela de Conteúdos e não me dá chance de criar uma nova classe de feição Batchpoint. Alguma sugestão? Obrigado antecipadamente!<\/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.
