Greasemap is a Greasemonkey script which adds a Google map to a page if it finds any geocodable addresses or other geotags on the page.

The map is placed in an iframe served up from Vinq.com - which gets around the restrictions that the Google maps key registration mechanism imposes.

Currently recognised locations are of the form

• 123 foobar street, anytown, MN 95125
• <meta name="geo.position" content="41.328,-110.292">
• <meta name="ICBM" content="41.328,-110.292">

The actual script is very short - it simply packages up any geotags on the page, together with any addresses recognised by a regular expression, and then passes it via a URL to the server which produces the iframe contents to be placed in an injected iframe tag.

All geocoding of addresses is done on the server. The server is thus a useful webservice in its own right. Take a look at:

http://www.vinq.com/greasemap.html?locs=801+spring+St,Seattle,WA

- it produces a twin map layout, showing a wide angle view, and a close-up.
