Grouping 2 sets of data together by location.
It would be great if you could report out each location from one data set and then group a second data set to the point in set one that it is closest to. So each entry from data set 1 could have mulitple entrys from data set 2 listed with it and give the distance from.

I now realize that this was originally intended for Analytics. I do think it could apply to all mapping.

Thanks for the idea. Although, this cannot be achieved in the UI today, it could be achieved in Apex code. Not sure if you are versed in Apex Code, but Geopointe comes with an Apex Class that is able to perform Radial Searches.
We have customers that have code (usually a trigger or a batch job) that associated the nearest x number of records to another record. Imaging having a a job that runs and the end result is a list of nearby records listed on your Account/Lead/AnyRecord page. It's very possible with what we have today, but does require code.
I understand that this idea is more about an easy way to do this in the UI and that's a great idea, but wanted to let you know about the code possibilities. Thanks for participating!
