Reverse Geocoding Demo

I put up a little demo.

This version will only reverse geocode streets that are addressable, meaning you need to click on streets that have actual buildings on them.
Most highways have no addresses so don't be surprised if you click on an interstate and get no resuts. I also have the search distance set very low and it will only return a range of addresses, it won't guess the exact number yet.

The demo is querying the database on my home machine which has very limited power and bandwidth so it may be up and down.

The power is out at my house, the demo won't work until it comes back on...

Hi John:

I like the sample you've put together... are you able to create a similar sample that one could type in the street address for the level of map shown and the address be geocoded to an exact lat/lon coord so that it could be located easily and shown on the map?

Also, I'm just curious on what you might have found out regarding your dual database idea... I did some research and your correct that currently only Oracle and MySQL seem to support the necessary spatial datatypes. Have anything to report on this?

Why don't you just plot that point on a google map and zoom in to see where it is?
