opstroom stroomgebied acres vanaf punt

Question

<\/HEAD>Hallo. Ik moet het aantal acres van opstroom stroomgebiedsgrenzen berekenen vanaf snijpunten tussen een voorgestelde uitlijning en oppervlaktewateren. Ik heb de ArcHydro-tools nog nooit gebruikt en werd doorverwezen vanaf de USGS StreamStats-site en vroeg me af wat de beste methode is om deze informatie te verkrijgen. Ik waardeer alle hulp - gewoon een aanwijzing in de juiste richting om te beginnen. Ik gebruik ArcGIS 10.4 Dank u!<\/P><\/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.
