KML File - opening and understanding

What is a KML file?

KML stands for Keyhole Markup Language. The KML file format was originally developed by Keyhole Inc. for the Keyhole mapping application. The Keyhole company and its software was acquired by Google in 2004.

The KML file format is now used primarily by the Google Earth application, although other mapping programs have been known to use this file format as well.

KML files use XML format to store geographic modeling information. These files contain lines, points, images and polygons. They are used to label locations and create overlay textures and camera angles for the maps that are created by the mapping applications.
