The Keyhole Markup Language (KML) was developed for Google Earth as a way to overlay user-generated content on maps. A KML file uses XML to record details like the place name and its coordinates on the latitude and longitude. Other data can be included in the file to make the view more specific, such as tilt, heading and altitude. Since its release in 2006, the KML file format has been increasingly adopted by more and more application developers. From its use in Flickr, Microsoft Virtual Earth to GPS applications on the phone, the KML file format has received industry wide acceptance. It is due to this accomplishment that the latest version of this file format has received accreditation from the Open Geospatial Consortium, an international voluntary consensus standards organisation, by making it a open standard for all “geobrowsers” like Google Earth, etc.
You can use KML files to send addresses or show a location to someone. To make one, you need to know the latitude and longitude of the place, and visit the online Google Earth KML Creator. Once made, the files can be viewed on any online mapping service that supports the KML file format. Here is a KML file displayed in Google Maps, showing all the national parks of India. Adding these KML tags to your Flickr albums will allow you and others to find your photos for any search conducted on their location name.
