KMZ — Nested Folders, a Second KML, and a NetworkLink
A KMZ that contains a second KML in a subdirectory, reached through a `NetworkLink` with a relative href, plus an overlay image two directories deep. Readers that only load `doc.kml` show the overlay but none of the three parcels.

Testing contract
Expected to pass- Scenario
- Load the archive and follow the NetworkLink to the linked document.
- Expected result
- Both KML documents load — the overlay from doc.kml and three parcel polygons from layers/parcels.kml — and the relative href resolves inside the archive rather than over the network.
What is a .kmz file?
KMZ is a ZIP archive containing a KML document and the resources it references. The main document is stored as doc.kml at the archive root, with icons, overlay images, models, and any additional KML files alongside it, so a single file carries an entire map presentation. Google Earth and most GIS tools read KMZ and KML interchangeably.
How to use this file
Use an example .kmz file to test KML readers, map importers, and archive-aware pipelines, verifying that doc.kml is located correctly, that relative resource paths resolve inside the archive, and that styles and overlays survive extraction.
How to use this file for testing
“KMZ — Nested Folders, a Second KML, and a NetworkLink” is a deterministic Novus Examples fixture for Geospatial, Conversion testing, Error handling. GeoJSON, GPX, and KML files with points, lines, polygons, and tracks — for testing map tools, route parsers, and geo importers.
Documented properties for this file: UTF-8 · LF · KMZ (ZIP-wrapped KML). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Geospatial fixtures publish one invented territory across formats, with the coordinate reference system and feature counts documented in specs. Convert or reproject and diff against the twin in the same group; edge-case geometries state exactly which assumption they are built to break.

- kmlKML — GroundOverlay and ScreenOverlayA georeferenced GroundOverlay pinned to the territory's bounding box and a ScreenOverlay anchored to a pixel position. Both reference images that are not present, which is the normal state for a bare .kml and the reason KMZ exists.
- kmlKML — MultiGeometry Mixing Points and a LineStringOne Placemark whose MultiGeometry mixes three Points with a LineString. GeoJSON has no equivalent single type for a heterogeneous set, so this must become a GeometryCollection — and converters that reach for MultiPoint instead lose the line.
- kmlKML — Polygons With innerBoundaryIs HolesTwo polygons that each carry an `innerBoundaryIs` ring: a parcel with a courtyard and a lake with an island. KML names its rings explicitly instead of relying on winding order, so converting to GeoJSON means deciding the winding rather than copying it.
- geojsonGeoJSON — Antimeridian Line Split per RFC 7946The same transect cut at the 180th meridian into a two-part MultiLineString, which is what RFC 7946 section 3.1.9 recommends. The split latitude is the linear interpolation of the unsplit twin, so the two files describe the same ground path.
- geojsonGeoJSON — Antimeridian Polygon Split into a MultiPolygonThe straddling block cut at 180 into two polygons that share an edge on the meridian — the interoperable form. Use it as the expected output when testing an antimeridian-splitting routine against the unsplit twin.
- geojsonGeoJSON — Clockwise Exterior Ring (right-hand rule violated)Both rings of the Mill Court parcel are wound the wrong way round: the exterior clockwise, the interior counter-clockwise. RFC 7946 mandates the right-hand rule, and consumers that rely on winding to tell holes from shells will read this polygon inside out.
