Google Earth Keyhole Markup Language Format | N/A | GIS Files |
The KML ( .KML) file extension is associated with Google Earth, ArcGIS Earth, and other geographic information systems (GIS) programs. It is primarily used for storing information related to geographic data, including map overlays, images, and points of interests. KML is an XML-based language employed by Google and other GIS applications and which allows users or developers to create new layers of data within GIS environments. The language structure of KML has been successfully incorporated into the Google Maps API and is now an official OGC standard.
KML File Purpose
KML allows users or developers to identify locations, draw shapes and mark points of interest on a map. Common uses for the KML file format are creating custom map overlays for web pages and providing data to textured 3D graphics programs. Sites such as Wikipedia and OpenStreetMap rely heavily on KML files in order to effectively show geographic information to their viewers.
Similar File Extensions
Similar file extensions include .KMZ, GEF, GEX, .GPX, and .IGC. Each of these formats are specific to various GIS applications.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .KML) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .KML extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .KML file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .KML extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .KML extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .KML file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .KML file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .KML file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .KML file) will be extended to the maximum.
It is also good to check
- if the .KML file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
