What is a .kmz file?

KMZ files are compressed archives containing a KML (Keyhole Markup Language) file and any supporting files, such as images, icons, and 3D models. KML is an XML-based language used to represent geographic annotations and visualizations in applications like Google Earth, Google Maps, and other geospatial software. The KMZ format allows for easy distribution and sharing of complex geographic data, as all necessary components are packaged into a single, compressed file. When opened, the KMZ file is unzipped, and the KML file is interpreted to display the geographic information, which can include placemarks, polygons, images, 3D models, and descriptive text. KMZ files are commonly used for sharing custom maps, geographic data overlays, and virtual tours. They are essential for visualizing and interacting with geographic information in a user-friendly and portable format. The compression also helps to reduce file size, making it easier to transmit and store large amounts of geographic data.
