KML vs KMZ: File Differences, Uses, and Conversion Workflows
A practical guide to Google Earth KML XML, compressed KMZ archives, embedded assets, and browser-based GIS tools.
KML is an XML document that describes geographic features, while KMZ is a ZIP archive that usually contains a main KML document and may bundle images, icons, or 3D models. Use KML when you need readable XML and KMZ when you need one compact shareable archive.
Core Concepts & Learning Progression
KML basics
Learn how Placemarks, Points, LineStrings, Polygons, Styles, and ExtendedData represent geographic content.
What KMZ adds
See how ZIP packaging can keep a main doc.kml with related assets in one file.
Import and troubleshooting
Understand NetworkLinks, coordinate order, invalid XML, and why a layer may open blank.
Choose the right workflow
View, validate, edit, convert, package, or extract with the focused GeoMap Suite tools.
Essential Technical Definitions
KML
Keyhole Markup Language, an XML-based open standard for geographic annotation and visualization.
KMZ
A ZIP archive containing a KML document and optionally related images, models, or icons.
Placemark
A KML feature that can contain a name, description, style, and Point, LineString, or Polygon geometry.
NetworkLink
A KML element that references content loaded from a remote URL rather than stored locally.
