What are KML and KMZ? KML is a file format used to display

geographic data in an earth browser, such as Google Earth, ArcGIS Explorer, and Virtual Earth.

A KML file is processed in much the same way that HTML (and XML) files are processed by web browsers.

Like HTML, KML has a tag-based structure with names and attributes used for specific display purposes.

KMZ is a compressed version of KML.
