What about My City?
If this is something you'd like to see for your city, let me know. :)
I can be reached at firstname.lastname@example.org, and please let me know if you're an interested observer, a city planner/official, or someone else.
We need something like this for planning/our department/research! Can you build it?
Quite likely, depending on what you're looking for. Statistics Edmonton is quite a bit more complex than it looks (everything you see, for example, are dynamic, on-the-fly objects created and rendered with the Maps API), and I'm able to do quite a bit more with individual points, tracking, and customized popups.
Who built this, the application, other questions?
You'll probably want to check out the About page, where I've put in more details.
