Intersect of two layers

spencermartin — Thu, 29 Mar 2012 12:36:19 GMT

Is it possible using rest services to perform a spatial query of an intersect between two layers? I want the returned featureset to have columns returned from each layer. I can do it in python already but I'm having trouble getting the script to run consistently on the fly from web page.

you can create a geoprocessing with intersect analysis (in option you can set what are fields in output : however default is ALL ) http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Intersect%20(Analysis)

Speno,
Can you describe the workflow and what you mean by intersection of two layers? Are they polygons? Is it the whole layer, just a few features, or just two features, or do you, etc. You should be able to use the intersect method of a geometry service. After which you can combine attributes.

and

Please post more detail on your workflow.
