KMZ and KML Compared:
When to Use Each Format

KMZ and KML are both popular file formats for storing geographic data, but they serve slightly different purposes. Here's how they compare:

What is a KMZ file?

A KMZ file is a compressed version of a KML (Keyhole Markup Language) file used primarily with Google Earth. It can include placemarks, images, paths, polygons, and even embedded 3D models.

  • Complex map presentations
  • Custom icons or embedded images
  • Visualizing data in Google Earth
  • Sharing entire map experiences (not just coordinates)

What is a KML file?

A KML file (Keyhole Markup Language) is an XML-based file format used to store geographic data such as points, lines, shapes, and overlays. Originally developed for Google Earth, KML files are now widely supported by mapping applications like Google Maps, QGIS, and ArcGIS.

What it's used for:
KML files are used to visualize GPS tracks, plan travel routes, mark specific locations, create interactive maps, and share geospatial data. They're especially popular among hikers, geographers, urban planners, and developers building location-based applications.

Frequently Asked Questions

What is a KML file?

A KML file is a Keyhole Markup Language file used to store geographic data like points, lines, and polygons in an XML format. It's commonly used with Google Earth and other mapping tools.

What is a KMZ file?

A KMZ file is a compressed version of a KML file. It can also include related assets like images or 3D models and is often used for bundling map data into a single package.

What is the difference between KML and KMZ?

KML is an uncompressed XML file, while KMZ is a zipped version that can include both the KML and additional media resources like images or overlays. KMZ files are more efficient for sharing rich map data.

Which is better: KML or KMZ?

It depends on your needs. Use KML for simple, human-readable files and debugging. Use KMZ when you want to include extra assets or reduce file size for sharing.

Can I open KML and KMZ files in Google Earth?

Yes, both KML and KMZ files are fully supported in Google Earth and most GIS software.
