Hi,
I`m currently working on a more complex SOE process that runs on our latest ArcGIS Server version 10.6.1 much slower then ever before. The process includes several Raster Geoprocessing Functions which are time consuming and currently processed synchronously without 64 bit background processing. I would really like to migrate this to an asynchronous background process but I can't figure out how to bring this together. Async/await doesn't seem to work with the common SOE project layout.
This is the major logic:
RestOperation doMyJob = new RestOperation("doMyJob", new string[] { "param1", "param2", "param3", "param4", "param5", "param6", "param7", "param8" }, new string[] { "json" }, doMyJobOperationHandler);
private byte[] doMyJobOperationHandler(NameValueCollection boundVariables,
JsonObject operationInput,
string outputFormat,
string requestProperties,
out string responseProperties)
{
... do a lot of stuff here
return getCutFillAreas(p_strDatasetName, p_Polygon, b_dBaseZ, p_dZFactor, p_bCreateFC, p_strConstantRasterPath, p_strCutFillRasterPath, p_strClippedRasterPath);
}
private byte[] getCutFillAreas(string paramA, IPolygon4 polygon, double z, double zFactor, bool createFC, string constRasterPath, string cutFillRasterPath, string clippedRasterPath)
{
JsonObject resultJsonObject = new JsonObject();
...do a lot of stuff here
executeClipTool((IRaster) iGeoDataset, clippedRasterPath, clippingEnv)
...continue here after clipping is done
executeAnotherGeoprocessingTool();
...continue
return Encoding.UTF8.GetBytes(someJsonObject.ToJson());
}
private void executeClipTool(IRaster inRaster, string outRasterPath, IEnvelope rectangle)
{
Geoprocessor GP = new Geoprocessor();
Clip l_clipTool = new Clip();
l_clipTool.in_raster = inRaster;
l_clipTool.out_raster = outRasterPath;
l_clipTool.rectangle = Math.Round(rectangle.XMin, 0) + ", " +
Math.Round(p_rectangle.YMin, 0) + ", " +
Math.Round(p_rectangle.XMax, 0) + ", " +
Math.Round(p_rectangle.YMax, 0)
executeGeoprocessingTool(GP, l_clipTool, null);
}
This is very simplified but it shows what I want to do. Basically I execute the tools synchronously and access results afterwards through file access.
Now I want to have my main function getCutFillAreas to run executeClipTool() and other functions with Geoprocessor as asynchronous Tasks. I tried
var result = executeClipToolAsync((IRaster) iGeoDataset, clippedRasterPath, clippingEnv).Result
with a Task<T> approach
Task<bool> clippingTask = Task.Factory.StartNew(() =>
{
return true;
}
return await clippingTask;
but then I get Task error.
Any help would be very appreciated!
