A few years back, when we were evaluating ArcGIS Server, I created a geoprocessing proof-of-concept service that received a lat/long and returned polygon IDs containing said point. There's now a need to actually use this feature, and within a high-volume environment, no less, so I've been looking to redevelop properly. There appear to be a few ways to go about this - Simple enough! However, what's the fastest, most performant way?
I have a map service containing a few thousand overlapping polygons (just need the layer to make the association) - I would like to send an x,y point (lat/long) and return a list of IDs from the map service.
I came across this thread:
Should I go about it this way, or should I use GeometryService?
