automatic detection of hot areas

[Don Park]

in order to identify hotspots of activity, i'd like to implement the following:

given a list of activities such as the creation of an access point
location record, or accessing an existing record, identify the 2D
area(s) that satisfy having X activities happen within Y meters of
each other.

the front page could have a text list of hotspots such as
Hotspots within the last 7 days:
31 new access points in Portland, Oregon.
120 location queries inside Austin, Texas.

Ideally, even the distance could be automatically determined to be
simply "interesting" events, such as 10 creations within 10 meters or
100 creations within 100 meters. The more events there are, the wider
the area can be to still be interesting.

Looks like a great idea. It will be useful for us to see where APs are
being added. Will be even cooler when there's lots of data. :)

How about heatmaps? That would be pretty cool to see. Maybe gheat (or
another heatmap API) can give us a text output of the hottest areas
for free without having to figure out that coding.

Oh... gheat, very cool. I just implemented a heatmap tile server for Google Maps, now that seems kind of silly to have done.
