Mash-Up Examples

Online Maps Mash-Up Examples
The following list of mash-ups reprent a variety of applications using a variety of data sources in an online map application.  I recently took down a couple of the examples because the services I was pulling from have gone off line or otherwise are unavailable.Most of the maps here are using the Google API, but check back as more APIs are added. Feel Free to copy code and share the wealth!
