The following code with a snap distance of 5 will fail with error code 2147483647.  But if I remove the parameter.  It will be working fine.  Any ideas how to bypass this issue?

 

string sIputRaster = @"C:\Support\PourPoints.tif";

string sFlowAccumRaster = @"C:\Support\FlowAccumulation.tif";
string sRaterPath = @"C:\Support\Snap.tif";

var parameters = Geoprocessing.MakeValueArray(sIputRaster, sFlowAccumRaster, 5, sRaterPath);

var cts = new CancellationTokenSource();
var results = await Geoprocessing.ExecuteToolAsync("SnapPourPoint_sa", parameters, null, cts.Token,
(eventName, o) =>
{
}, GPExecuteToolFlags.None);
if (results.IsFailed)
{
   MessageBox.Show("Failed to create fill layer. Error " + results.ErrorCode);

return;
}

Hi,

As I mentioned in ArcHydro tools question spatial analyst output parameter can migrate. Try specify snap distance after output raster path. In addition check validation messages sent from geoprocessing tool execute.

Thanks a lot, @GKmieliauskas !  After I specified distance after the output raster path, it solved the problem!
