KML vs KMZ for Google Earth: Differences, Import Tips, and Troubleshooting
A practical comparison of KML and KMZ for Google Earth, including import steps, asset behavior, coordinate mistakes, and browser-based checks.
KML is an XML map document; KMZ is a ZIP archive that contains a KML document and may bundle related assets. Use KML for debugging and readable data, and KMZ for compact sharing in Google Earth.

KML vs KMZ: What Is the Difference?
KML is readable XML containing geographic Features such as Placemarks, Points, paths, polygons, styles, and descriptions. KMZ is a ZIP archive that usually contains a main doc.kml and may include local images, icons, sound, or 3D models. Google Earth can open both formats.
Which Format Should You Use?
Use KML when you need to inspect or edit the XML, troubleshoot coordinates, or convert the geometry into GeoJSON, CSV, or GPX. Use KMZ when you want one compact file for sharing a KML layer with its local assets. Keep the original archive when asset fidelity matters.
Why Does Google Earth Show a Blank Map?
Common causes include malformed XML, longitude and latitude reversed, coordinates outside valid ranges, missing referenced assets, or a NetworkLink that requires a remote server. Run the file through a KML Validator before importing again.
Check XML, namespace, Placemark content, and coordinate bounds before blaming the map viewer.
