The code below with parameters in 14th line fails to run slope tool and get expected result
public SlopeTool(string inRaster, string outRasterName, string workspace, string prjFilePath)
{
_inRaster = inRaster;
_outRasterName = outRasterName;
_workspace = workspace;
_prjFilePath = prjFilePath;
}
public async Task<IGpResult> ExecuteAsync()
{
try
{
var slopeToolParameters = Geoprocessing.MakeValueArray(
_inRaster, "PERCENT_RISE", 1
);
var gpResult = await Geoprocessing.ExecuteToolAsync("sa.Slope", slopeToolParameters);
if (gpResult.IsFailed)
{
MessageBox.Show("Tool Failed");
}
return new GpResult(gpResult);
}
catch (Exception ex)
{
MessageBox.Show($@"Error during Slope Tool operation: {ex.Message}");
return new GpResult(null);
}
}
But this code below runs and succeeds with the parameter in 14th line
public SlopeTool(string inRaster, string outRasterName, string workspace, string prjFilePath)
{
_inRaster = inRaster;
_outRasterName = outRasterName;
_workspace = workspace;
_prjFilePath = prjFilePath;
}
public async Task<IGpResult> ExecuteAsync()
{
try
{
var slopeToolParameters = Geoprocessing.MakeValueArray(
_inRaster
);
var gpResult = await Geoprocessing.ExecuteToolAsync("sa.Slope", slopeToolParameters);
if (gpResult.IsFailed)
{
MessageBox.Show("Tool Failed");
}
return new GpResult(gpResult);
}
catch (Exception ex)
{
MessageBox.Show($@"Error during Slope Tool operation: {ex.Message}");
return new GpResult(null);
}
}
I can also run it in Arcgis pro python command line this way
arcpy.sa.Slope('DEM_AB_Clip1.tif', 'PERCENT_RISE', 1)
What is the problem in my 1st code and how to get expected result ?
