akry povodí nad bodem

Question

<\/HEAD>Dobrý den. Potřebuji vypočítat rozlohu povodí nad body průsečíků mezi navrhovanou trasou a povrchovými vodami. Nikdy jsem nepoužil nástroje ArcHydro a byl jsem nasměrován z webu USGS StreamStats a zajímalo by mě, jaká je nejlepší metoda pro získání těchto informací. Ocením jakoukoli pomoc – jen ukázku správným směrem, abych mohl začít. Používám ArcGIS 10.4. Děkuji! <\/BODY><\/HTML>

Hello everyone. Well, it turns out the the StreamStats ended up working which saved me TONS of time. I think I must've been trying to use the application as they were finalizing v4 development because the last day I tried using it everything came together.

I appreciate everyone's help and input. Thanks!

Another helpful tool set can be found using HEC-GeoHMS. This is a free ArcMap tool that has the basics of the Arc Hydro tool.

The geoprocessing tools for Arc Hydro are in this tool but they are somewhat simplified. That is, you could use the GeoHMS tools just like the Arc Hydro tools. GeoHMS was created by ESRI for the US Army Corps of Engineers Hydraulic Engineering Center (HEC). It has additional tools to build HEC-HMS models, something I suppose you don't need. When you install HEC-GeoHMS it will also install the compatible Arc Hydro tools.
