What is KML file?

File with.KML extension contains 3D geographic modeling data saved in XML-based format. KML files can store information about:

  • Points,
  • Lines - paths,
  • Rectangles,
  • Images,
  • 3D models,
  • Text descriptions.

Data stored in KML files can be used for marking and describing geographical locations, or adding various camera angles or overlay textures. Each location is described with its coordinates (latitude and longitude) following the WGS84 standard, and optionally with additional third coordinate – height above mean sea level, by default set to 0. ‘Camera view”’ or time stamp can also be defined. KML format shares some similarities with GML format.

KML files are commonly distributed as KMZ files, which are nothing more than KML files compressed using ZIP method. The name Keyhole Markup Language was derived form the name of an software application developed by company that developed this markup language used by KML files. In 2004 the company was bought by Google and the technology was used in Google Earth project, which allows viewing and editing KLM offline and online. In 2008 Open Geospatial Consortium standardized the KML 2.2 language as open format for geo-browsers.

We hope we helped you solve the problem with the KML file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the KML file (apart from the lack of the proper application installed).

First - the KML file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the KML file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the KML file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the KML file has not been completed and it cannot be opened properly).
