About KMZ
KMZ is a ZIP-compressed version of a KML file. It typically contains a doc.kml file at its root along with any referenced images, icons, or overlays. KMZ files are smaller than their KML counterparts, making them easier to share by email or embed on web pages. They are supported by Google Earth, QGIS, ArcGIS, and many online mapping tools. KMZ files can be uploaded directly to Google My Maps.
Strengths
- +Smaller than raw KML
- +Can bundle images and overlays
- +Widely accepted by mapping tools
About GML
Geography Markup Language (GML) is an XML-based OGC standard for encoding geographic features. It is the mandatory format for the EU INSPIRE directive and is commonly used in Web Feature Services (WFS) to deliver geospatial data over the web. GML files are highly interoperable across GIS platforms and are natively supported by GDAL, QGIS, ArcGIS, and GeoServer. GML can represent complex geometries, coordinate reference systems, and rich attribute schemas, making it the format of choice for authoritative government and infrastructure datasets.
Strengths
- +OGC standard — maximum interoperability
- +Mandatory for EU INSPIRE datasets
- +Supports complex geometries and CRS metadata
- +Native support in QGIS, ArcGIS, and GeoServer
Frequently asked questions
Q.Is plain KML also accepted?
Yes. For .kml files use the KML to GML converter on this site — both produce identical GML output.
