hoe kan ik FOUT 010151 oplossen met Hec-GeoRAS?

Question

<\/HEAD>Hallo iedereen,<\/P> <\/P> Ik gebruik ArcGIS 10.6 en HEC-GeoRas 10.6. Ik moet een GIS-project maken; eerst voer ik mijn stationaire simulatie uit in HEC RAS, exporteer alle gegevens uit HEC-RAS en sluit dan het programma af. Vervolgens converteer ik in ArcGIS met GeoRAS SDF naar XML-bestand, stel mijn laag in, maak de nieuwe analyse aan en voer een wateroppervlaktegeneratie uit, alles goed zonder problemen. Ten slotte, wanneer ik kies voor: "Overstromingsvlakte afbakening met rasters" krijg ik deze fout:<\/P> <\/P> System.Runtime.InteropServices.COMException(0x80041098):FOUT 010151:<\/STRONG> Geen features gevonden in C:\........\Steady_PF\fdtemp.shp. Mogelijk lege feature class.<\/EM> bij ESRI.ArcGIS.GeoAnalyst.RasterConversionOpClass.RasterDataToPolygonFeatureData(IGeoDataset dataset, IWorkspace pWorkspace, String name, Boolean weeding)<\/EM> bij HECGeoRAS.clsMFloodGRIDIntersection.GridToPolygon1(IRaster pRaster, IGeoDataset pGeoIn, IWorkspace pWS, String sName, Boolean sWeeding)<\/EM><\/P><\/P>Ik kan het niet oplossen, kan iemand mij alsjeblieft helpen?

Hi Kurt, do you happen to know what exactly causes this error? What exactly is 'fdtemp.shp' and why does it show up empty? I tried running the same tool and had the same error, the process crashes at the step "Converting floodplain GRID to polygon for profile (name)" and then it says "Could not convert Grid to Polygon! for profile (name)". If the process crashed here, would it not imply that the process was successful up to the subtraction of the contour grid and water surface grid? And if this were the case, is it possible to take the data from the output grid of the subtraction and use the Raster to Polygon tool to create the polygon in the Arcmap? Thanks in advance.

Best regards,

Kevin

Estefania,

Looks like you got your cross sections to come into ArcGIS.  Make a TIN using your cross sections as a contour data type and the water surface elevation field as the elevation source.  Convert the output TIN to a raster with the same cell size as your DEM.  Looks like your DEM might also be a TIN.  If so, convert this to a raster as well.  Use the Minus tool in Spatial Analyst to get the difference, which will also be a raster.  Create a contour using Contour List at an elevation of zero.  This line indicates where the terrain elevation is equal to the water surface elevation.  It also represents the floodplain boundary as a line.  If you connect the endpoints of this line to make a closed polygon, you can then convert it to a floodplain polygon and edit it accordingly.

You can put this into Model Builder to help you automate the process for future iterations.

Hope this helps,
