Yesterday, Google announced KML support in Google Maps. KML is a markup language like XML that defines data to be shown on a map. I use KML on Where's Tim to show my current location inside of Google Earth, so I was very excited...until I tried it.
My KML file is an .aspx page that returns a content type of "application/vnd.google-earth.kml+xml", so when you click on it...it opens in Google Earth. So I put the address of my .aspx in the query string as instructed by Google and I got a "could not be displayed because it contains errors". So I thought, ok...maybe it has to have a .kml extension, so I downloaded the file and ftp'd it to here. And when I put that url in the query string, I got a File not found error. So I tried a file that Frank Taylor made a while back...and it worked.
Maybe Mike still has the ear of a mapping guy over at Google...If so, ask him what do I need to do to make my KML work with Google Maps?
UPDATE: My export history to KML page works inside Google Maps. Maybe it just doesn't work with a single point. Or maybe I am defining my single point wrong.
