Local Geoprocessing without packages

GeorgeFaraj · ‎11-09-2012

I'm opening feature layers from map packages and now I need to run tools such as Union, Buffer, Intersect, etc. dynamically on those layers, then add the results as a new layer in the map. What is the best way to do this locally without using pre-modeled packages?

Hi,

The task within the service takes the same name as the model name - from your screenshot it looks like you should be using "BufferModel" in your code?

Cheers

Well, that was a quick reply! 🙂

I actually noticed that and edited the error message above. This is the error I'm getting now:

Bad request: POST GPServer/BufferModel/execute The 'execute' operation is not supported.

The type of method call you make: ExecuteAsync or SubmitJobAsync needs to correspond the the GPServiceType you start the Local GP Service as (GpServiceType.Execute, etc) - see http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client.Local~ESRI.ArcG... for more info.

It's an architectural detail of the way the RuntimeLocalServer manages the LocalGPService, but it's a choice you need to make. Typically the Execute (synchronous) type of service should only be used for very quick models/taks.

Cheers

Thanks. I had forgotten to pass Execute in the service's constructor. Now I'm getting another error. Any idea how to figure out what's wrong now?

Unable to complete operation.

EDIT: Found more details about the error inside the failed event args:

[0] = "Error executing tool.: ERROR 000800: The value is not a member of parcels."

'parcels' is the name of my FeatureLayer. It's also the name of the layer I used as a sample input when I ran the tool in ArcMap.

You've got a couple of options:

#1. Iterate over the GPMessages

e.g.

geoprocessor.ExecuteCompleted += (s1, e1) =>
                        {
                            GPExecuteResults results = e1.Results;

                            foreach (GPMessage message in results.Messages)
                            {
                                // Do Something e.g. Console.WriteLine(message.Description);
                            }
                        };

geoprocessor.ExecuteAsync(new List<GPParameter>());

#2. Take a look at the actual RuntimeLocalServer log files - sometimes there may be additional info in there.
Use the LocalServerUtility (accessed from the Start Menu) to enable logging for your central developer Runtime install then rerun your code. This will generate a log file - you can use the LocalServerUtility to view these logfiles, or at least the location of them anyway - they're just textfiles written to your temp folder.

The ExecuteCompleted handler doesn't get called, only the Failed handler does. I edited my reply above with more info, but here it is too:

Found more details about the error inside the failed event args:

'parcels' is the name of my FeatureLayer. It's also the name of the layer I used as a sample input when I ran the tool in ArcMap.

EDIT2: I should post my code:

var gp = new Geoprocessor(GetGeoprocessingService().UrlGeoprocessingService + "/BufferModel");

var parameters = new List<GPParameter>();

var gpFeatureRecordSetLayer = new GPFeatureRecordSetLayer("InputLocation");

foreach (var graphic in (MyMap.Layers["parcels"] as FeatureLayer).SelectedGraphics)
{
 gpFeatureRecordSetLayer.FeatureSet.Features.Add(graphic);
}

parameters.Add(gpFeatureRecordSetLayer);
gp.ExecuteCompleted += (senderObject, gpExecuteCompleteEventArgs) =>
{
};
gp.Failed += (senderObject, taskFailedEventArgs) =>
{
};
gp.ExecuteAsync(parameters);

I fixed my input parameters, they were not set correctly. I got it to complete, but got no results back. Apparently this is because I had no output parameter set up. I went back to ArcMap and set the output of the Buffer tool to be a Model Parameter. I am now getting this error:

Error executing tool.: ERROR 000210: Cannot create output C:\Users\gfaraj\AppData\Local\Temp\arcgisruntime_7576\buffertest1\jobs\_\j8adb6feeb81f41cab48b4ec3f22a011d\scratch\scratch.gdb\BufferResult
Failed to execute (Buffer).
Failed to execute (BufferModel).
Failed to execute (BufferModel).
Failed to execute (BufferModel).

Any ideas?

GeorgeFaraj · ‎01-22-2013

Nevermind, I got it working. I was passing my input parameter with the wrong name. Thanks to everyone who helped!

MichaelBranscomb · ‎01-22-2013

Glad to hear you got it working.

There's a sample in the WPF Sample App which could help in future - GPTaskInfo, it spins up a new LocalGPService based on your GPK and lists the parameters, etc. Looks like this: http://resources.arcgis.com/en/help/runtime-wpf/samples/index.html#/GPTaskInfo/02q20000004w000000/

Question: Is there a way for the resulting feature set to contain the attributes of the input feature set parameters? I'm getting back the parameters that were in the schema I used in ArcMap, and not the attributes of the actual features I'm passing to the geoprocessor.
