Keyhole Markup Language (KML)

KML is an XML based markup for geographic data. It is commonly used with Google Earth and Google Maps, but other geographical data viewers can use it as well.

Example

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

Explanation

This example is for a Lifemapper projection. In Google Earth or Google Maps, it will produce an overlay that will display the projection. Lifemapper environmental layers look very similar, but occurrence sets specify several placemarks and each specifies a point.
