Yahoo has a geocoder that is very nice and allows up to 5000 hits per day:
http://developer.yahoo.com/maps/rest/V1/geocode.html
this will return a lat/long point for any address in the US that you can
use to zoom to in your map.
you might want to look at openlayers.org, as well...

Subject: newbie needs help in mapping counties in color
Hi Guys,
I am a newbie and need a very simple application. I am sure mapserver
(and kamap) support it out of the box. I just need to be pointed in
right direction. I have been working on this for 10 days, so I have some
idea of mapserver now.
I need to show a map of US streets with each county colored differently
based on the cars/household density. If you zoom in to a state level,
then map should color each "block group" rather than each county. That
is all I need. Here are my problems with this:
1. How can I convert TIGER street maps to shape files? I was able to
find commercial version of these files but without geocoding data. Since
I need geocoding data (to provide ability to zoom to an address), should
I encode the data myself to shape files? If so, how can I do it, just
some pointers would be very helpful.
2. Also, I put each county file on a separate layer and that works fine
but I do not think that is the right way to do it. Can I put all
counties in one layer? If so, how do I do it given that there is a
separate shape file for each county? If I join the shape files, how can
I color them differently?
This is all I need. Any pointers, help, prebuilt "map files" etc. would
be very helpful.
Thanks a lot for your help
Ravi
