Overview

KML (Keyhole Markup Language), an XML schema originally developed for Google Earth to describe shapes on a map has been supported by VE since version 6.0 was released and has remain unchanged up to VE 6.2.  The common questions this series will address are "Which KML features does VE support?" and "How do I use these features?" for developers with no KML experience.

KML Quickstart

If you haven't already, take a look at the Interactive SDK (http://dev.live.com/virtualearth/sdk/ ) and MSDN (http://msdn.microsoft.com/en-us/library/bb429606.aspx ) on to see how to load a feed into VE. I had trouble loading KML locally (GeoRSS was okay) using any browser even with a website setup through IIS.  I found that uploading my KML file to SkyDrive and referencing the URL worked.  Finally, you'll need to open the google KML documentation page (http://code.google.com/apis/kml/documentation/kmlreference.html) to follow along.

Here is a sample KML loader taken from the SDK with a few modifications:
