Viewing Asyncronous Map Result Image Layer

eddiequinlan — Tue, 21 Aug 2012 20:49:28 GMT

Hi All,

Not sure if this is a flex issue or geoprocessing issue, but here it goes....

I have a basic geoprocessing model which performs a spatial select on a parcel layer and shows what parcels are selected (very basic at this point). The model/.mxd runs fine.

I???ve published this model as an asyncronous result map service.

I???ve tested this model thru the ArcGIS Services Directory, by inputting some coordinate input values. This runs fine and I can see the record count and attributes of the query.

First Question????????? Can I run the same request thru the Services Directory and see the results as a ???map result??? either graphic or layer on a map?

My FLEX app runs this map service as an asyncronous job and I can see the records/attributes of the request. What I can???t see is the resulting map image.

I don???t know if my published map is set correctly to display the map results (the reason for my first question), or if my FLEX app is not coded properly.

If I tweak my code and run a syncronous job, I can loop thru the results and shade the map correctly. I???m trying to use the asyncronous method because of the potentially large amount of processing. I???ve read just about all the documentation I can find and have tried numerous variations of coding, map service configurations, etc and still cannot get the results.

If I could test the results at the Services Directory and it works, then I would think my FLEX coding is wrong??????.

Any Suggestions?????????

Painfully,
Eddie

After the job is complete, you can call getResultMapServiceLayer() or getResultImageLayer() and add the layer to your map.

See:

Thank you for the response Dasa and by the way I thought your lecture at the San Diego conference was the most entertaining and informative.

I'm using ArcGis 10.0, therefore I've only tried the getResultImageLayer () method with no luck. Since my last post, I did run the model at the ArcGIS services directory; received back attribute results; and then tried viewing those results in Google Earth. Google Earth recognized there was data, but visually I still didn't see any mapping symbology.

thanx,
Eddie

It sounds like your result map service may not be enabled.

This may help are you may need to contact Esri support at http://support.esri.com

Hi Dasa,

As far as I can tell my map service results are enabled. Here is a copy of the server settings...........

In the ArcGIS10.1 example, it describes adding the map results by "right clicking" the results in the .mxd and publishing them. In 10.0 I don't see any option/method to do this. The only place I see is at the Server; as in the text above?

When you run the task from the services directory and view the result parameter, does it show you an image?

Re: Viewing Asyncronous Map Result Image Layer

eddiequinlan — Wed, 22 Aug 2012 19:39:47 GMT

Hi Dasa,

I have some more info......

My model still runs correctly, but now in the Services Directory the results parameter only shows a "graphic X" with xmin, xmax, etc.. when I open this in Google Earth it will now show this X in the approximate location. There is no longer any attribute data shown in the results parameter.

However, in the \arcgisserver\arcgisjobs\job_id I can access the corresponding .shp file; add it to ArcMap; view the .shp file; and open the attribute table.

In my opinion, the results are not getting to the service directory properly; or configured properly.

Any other suggestions?
Eddie

Hi Dasa,

Sorry I keep responding to myself, but things are beginning to work and I'd like others to know.

This makes no sense to me, but I tried changing the "Result Map Service" in the Geoprocessing Service Parameters to "none". The results now show all the returned feature attributes in the "Services Directory" and the map results are viewable thru Google Earth.

Hi all,

By using Fiddler and "trace" in Flex, I think I've found the issue. After my "jobcomplete" function runs and i get a positive result, I then run per the examples:

var myImageLayer:GPResultImageLayer = GP_async.getResultImageLayer(event.jobInfo.jobId,"Results_shp",imageParameters);

where the imageParameters have already been set.

Thru fiddler I can see the 500 error code and object not set. Now I'm at a loss. Help.

If I run the same code but as:

GP_async.getResultImageLayer(event.jobInfo.jobId,"Results_shp",imageParameters);

fiddler shows no errors. I'm not sure why the GPResultImageLayer is not set. Again as stated previously, I can run the request thru the services directory; get returned results; and view those results thru the Google Earth view.

thank you,
Eddie

DasaPaddock — Thu, 23 Aug 2012 19:14:13 GMT

You can only use getResultImageLayer() if there is a result map service.

You can use Geoprocessor.getResultData() if your service is returning a FeatureSet and then add the features to a GraphicsLayer.

Reference:
http://resources.arcgis.com/en/help/flex-api/apiref/com/esri/ags/tasks/Geoprocessor.html#getResultData()

Sample that calls getResultData():

Re: Viewing Asyncronous Map Result Image Layer

eddiequinlan — Thu, 23 Aug 2012 19:30:28 GMT

Hi Dasa,

Thanx again for the help. Yes, I'm aware of the two different methods but just can't get the getResultImageLayer() method with the resulting map service to work correctly. I've given up on that method, and I am using the getResultData() asyncronous and then adding the results as graphics. In the long run this might prove to be a better way for my needs. The only drawback I'm finding is that if my return results start to get above 10,000 records adding the graphics takes a while, and the client side can time out. I've limited the attributes in the results shp/table to only those attributes I need, I have also indexed some of those attributes, and created a spatial index. Do you have any suggestions on the performance?

Also, I've noticed that when performing a large spatial query thru the map service, the resulting .dat file in /arcgisserver/arcgisjobs/<path> gets extremely large. My initial data set is only 113mb with 350,000 records, but when I run a map service geoprocessing query on "say 10,000" records the .dat file size exceeds 250mb. What's up with that??????

Thank you for your patience,
Eddie

Using a result map service would be a good option if you have lots of data. I'd contact Esri Tech Support for both issues.
