Keyhole Markup Language (KML)

KML (Keyhole Markup Language) is an XML-based file format used to display geographic data in an Earth browser, such as Google Earth or Google Maps. KML is used for visualizing and sharing geographic information in a way that can be easily understood and navigated by users.

KML files contain a variety of data types, including point, line, and polygon features, as well as images, text, and 3D models. KML files can also include information about the appearance and behavior of features, such as color, transparency, and pop-up information boxes.

KML files can be created using a variety of tools, including Google Earth, Google Maps, and specialized GIS software such as ArcGIS or QGIS. KML files can be shared through email, file-sharing services, or web servers.

KML is widely used in a variety of industries, including urban planning, environmental management, and tourism. It is also used by government agencies, emergency responders, and researchers to share geographic data and information.
