Google Earth/Maps Icons
The following is a collection of icons Google makes available for Google Earth and Google Maps.
This is a useful cheat sheet showing all the standard icons to use in Google Earth, Google Maps, and other map related applications. All icons are PNG images and include standard symbols for weather, highway, roads, numbers, arrows, etc. The icons below are the official Google icons shown in one place for a handy reference.
You can insert the URLs below into Google Earth when editing the icon for a given placemark [see instructions] or use in the KML you create programmically.
Note: The track icons are treated special in Google Earth. If you specify to use the gx:Track extension as used for GPS-tracks and specify a Style using the http://earth.google.com/images/kml-icons/track-directional/track-0.png icon (shown above) then the icon is dynamically changed to appropriate icon using the computed compass heading from the previous position. The URL http://maps.google.com/mapfiles/kml/shapes/track.png can also be used in KML for the track icon style for the same behavior, but in this case the URL itself doesn't resolve if accessed directly in a web browser and results in a HTTP 404 not found error.
The pushpin icons for example have the hotspot defined at the lower-left corner of the icon.
The pal2 through pal5 icon groups were used by earlier versions of Google Earth and no longer part of the core icons. In fact, if you create a custom icon style with any of the pal image URLs then Google Earth will automatically remap the URL to one of the standard icons such as the following:
