Thanks, folks, for the suggestions. I have shown both the notes-with-coordinates and the target to the users. Google has a callout without any hassle, so that's what they want. Guess it will have to be custom coded, which is a shame. Bing has a no-hassle callout, too. It'll have to be custom code, I guess.

Users came to me with another "make it like Google" request. They click on the Google Maps map, right-click "What's Here" and get a green arrow. Then click the green arrow and they get what they want. A nice arrow and a popup with coordinates in both decimal degrees and DMS. Perfection! The only reason they are even asking for something else is that we'd like to add our own data on top. As far as I can tell, AGS Explorer has no built in method to do this and I haven't seen a tool for it in the gallery. Anyone have a way to get this functionality, short of coding from the SDK? Thanks.

Thanks for the various suggestions. I cannot comment on the performance of Generate Near Table, since I am running with a Basic license. The complaint I have is why does ArcGIS seem to include all the lines inside the boundary box of the selecting points, even if the search distance is small? If one point is used, the process is very fast. Add a second point diagonally across the extent of the streets and all of them appear to be examined.

The same Select Layer by Location is now being run with 115,000 points and 20+ million streets. It looks like ArcGIS is trying to bring in the entire dataset - 3 GB of memory usage and climbing.

Right now, I have a few hundred points and 20+ million lines. Over and over, I need to select the lines that are closest to the points. If I use Spatial Join, it takes an absurdly long time. If I try to narrow it down by using Select by Location first, it takes an absurdly long time, reading in every single line envelope that falls within the bounding box of my points. All of them. This problem has been happening for at least a year (10.0), and it cripples performance. We work around it by scripting by location with each point selected instead one at a time, but this is not acceptable. Will there *ever* be a fix for this? Is there a better workaround? Both sets of features are in a local file geodatabase. I'm on 10.1 SP1 now.

[the presentation can be found by searching the proceedings for '3D'] 1. The Road Ahead slide - can you clarify the expected release period, roughly, of this functionality 2. Will similar functionality be available to other ESRI APIs. Which ones, and at the same time? Thanks very much I'm pretty excited about this....

Thanks for the reply, Melanie: I might not have been clear. The features to be selected are in a file geodatabase feature class, so they do have Object IDs. The XY events are going to be used to do the selecting - they are not being selected themselves. I can do such selecting with an arcpy geometry object, so it should also work with the XY events. Does this make sense? Maybe I am still missing something. - Harry

Did you trying exporting the event layer out to a shapefile first? Yes, that works fine. Why doesn't using the XY event layer directly work OK? I inherited a working Python script that as of last year (February 2012) used an XY layer directly. Now it doesn't work. I can even use a hand-built arcpy geometry object as the input for Select By Location. If that works, this should too.

I create an XY event layer in GCS_WGS_1984. Using this layer as the selecting features in Select by Location fails with a 999999 error. If I use this layer as the target, or in Buffer, the tool fails with 000339: ...does not have OIDs. Is this why it is failed in Select by Location? I inherited a python script that was written to use such as layer as the selecting features. Did this used to work? Why doesn't it now? I would think that the OIDs for the selecting layer should not matter.

Mark: Thanks for the information about the Bing Key. That's a big relief to us. - Harry
