Comparison of KML and XML file extensions

Google Earth allows you to view the information placed at the top of the map for any particular area, such as the census or marketing information and images. The type of file used to view this information in the program is called KML.

The KML or Keyhole Markup Language file extension format is used to store geographic data including navigation maps and other driving instructions. This format was developed primarily for Google Earth desktop mapping software. KML was developed as a way to store geographic information that is readable by different mapping programs in a standard way.

Another online mapping application, Google Maps, also provides support for importing XML files to the Internet; so that users can view and edit browsing data. As the KML extension is a format developed by Google, it only takes a few mouse clicks to add the data to Google Maps.

The XML file extension stands for eXtensible Markup Language. It is a type of semantic programming language used to obtain and present data to users. XML files use this extension and can be easily read by most web browsers and some computer programs. These documents are used on many sites on the Internet and the extensive browser support for XML files allows the data to be displayed without users noticing any difference. These files are used in many applications that involve dynamic data or changes. XML is typically used to transfer data between two websites. There are also other ways to identify them besides the extension.

The KML and XML extensions have totally different purposes. KML is associated with Google Earth, while XML is mainly used to transfer data between two websites.
