[[KML]] is the Keyhole Markup Language. It's an [[xml]]-based language that allows to create content for Google Earth and Google Maps.

It allows to create [[viewpoints]], [[placemarks]], [[paths]], [[shapes]], [[image overlays]] and [[3D buildings]]. It also allows to embed customized [[html]] code in the [[placemarks]].

==Sample kml file==

=== Placemarks with custom html code ===
[http://maps.google.com/maps?f=q&q=http%3A%2F%2Fnfist.ist.utl.pt%2F%7Eguillaume%2FMohidBeachcams_NetL.kml&btnG=Search+Maps Here's] a simple [[kml]] file that adds a [[placemark]], a [[viewpoint]] for it, and embeds some custom html code:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">

=== Network links ===
[[Network links]] can be very useful when providing early releases of beta services. This way, the developper may continue to upgrade the production version of the [[kml]] file, by providing to the users a file that contains a link to it.

[http://maps.google.com/maps?f=q&q=http%3A%2F%2Fnfist.ist.utl.pt%2F%7Eguillaume%2FMohidBeachcams_NetL.kml&btnG=Search+Maps Here's] a simple kml file that adds a [[network link]] to another [[kml]] file:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">
<NetworkLink>
<name>MohidBeachcams</name>
<open>1</open>

</NetworkLink>

[[Kml2Mohid]] is a little [[ruby]] program that converts [[Google Earth]] [[kml]] files into Mohid [[GIS]] data files.
