I have multiple map services, Capital Improvement Projects, Water (stuff), Wastewater (stuff) ,etc. etc. Each of these map services may have lots of layers...
We want to build a tool that will identify anything within a polygon, from many map services and many layers on each map service.
I would like to do some kind of query all or identify all (for a POLYGON)
What is the best approach...
I cheated initially by pre-processing and make a phony feature class with the assets from all those other areas into a single feature class and doing a single query on this layer, but this is growing too big and now I have a mix of points, lines, polygons.
Can arcgis silverlight identifytask work on multiple layer ids? Can you identify on a POLYGON AOI instead of just a point?
