Data Extraction Service

Question

Hi,

At the following URL, http://resources.arcgis.com/gallery/video/arcgis-server/details?entryID=4A08A4AE-1422-2418-888D-E79B9C266306, ArcGIS Server Product Manager Ismael Chivite describes how to use the Data Extraction Service with the Flex Viewer.  Is there a similar step-by-step guide for doing the same with Silverlight?

Thanks,
Paul

Hi,
 
My AOI does not work,
 I also have the Rectangle issue. But the polygon Area_Of_Interest works for me.

Would you mind sharing your C# and Python code?

I think I am getting closer.  I modified my C# code to send a Polygon instead of a Geometry. I am now sending the following for the AreaOfInterest:
{"geometryType":"esriGeometryPolygon","spatialReference":{"wkid":54016},"features":[{"geometry":{"spatialReference":{"wkid":54016},"rings":[[[-9644076.38419297,5796738.17420953],[-9644076.38419297,7907391.71990488],[-5457946.85189718,7907391.71990488],[-5457946.85189718,5796738.17420953],[-9644076.38419297,5796738.17420953]],[[-9239534.45460135,5761560.6151146],[-9239534.45460135,7801859.04262011],[-7216824.80664331,7801859.04262011],[-7216824.80664331,5761560.6151146],[-9239534.45460135,5761560.6151146]]]},"attributes":{}}]}

If I execute the GP task via the REST interface, I get the following results:
Job Status: esriJobFailed

Line 330 in the Python script corresponds to:
zipFolder = clipAndConvert(layers, areaOfInterest, featureFormat, rasterFormat, coordinateSystem)

I am not sure what that error refers to. It does not tell me which parameter it is having problems with!
