GeoJSON — Mixed-Geometry FeatureCollection
All seven RFC 7946 geometry types in a single FeatureCollection. Formats with a single-geometry-type-per-layer model — shapefile, most database tables — cannot hold this in one layer, so it is the fixture that reveals how a converter splits or refuses it.

Testing contract
Expected to pass- Scenario
- Convert the collection to a single-geometry-type format such as a shapefile layer.
- Expected result
- The converter either splits the output into per-type layers or reports a clear error — it never silently drops the types it cannot store.
What is a .geojson file?
GeoJSON is a JSON-based format for encoding geographic data structures such as points, lines, and polygons, along with their properties. It uses WGS84 longitude-latitude coordinates and standard feature and feature-collection objects. It is a common interchange format for web mapping and GIS.
How to use this file
Use an example GeoJSON file to test geometry parsing, coordinate handling, and mapping libraries or GIS pipelines that render or analyze spatial features.
How to use this file for testing
“GeoJSON — Mixed-Geometry FeatureCollection” is a deterministic Novus Examples fixture for Geospatial, Conversion testing, JSON parsing. 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 · GeoJSON (RFC 7946). 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.

- geojsonGeoJSON Geometry — LineStringA one-feature FeatureCollection holding the four-vertex Coast Road, so a reader can be exercised on LineString in isolation. Coordinates come from the Kestrel Bay territory, so the same shape appears again in every other format in this category.

- geojsonGeoJSON Geometry — MultiPointA one-feature FeatureCollection holding three harbour buoys, so a reader can be exercised on MultiPoint in isolation. Coordinates come from the Kestrel Bay territory, so the same shape appears again in every other format in this category.
- geojsonGeoJSON Geometry — MultiPolygonA one-feature FeatureCollection holding the three parcels as one geometry, so a reader can be exercised on MultiPolygon in isolation. Coordinates come from the Kestrel Bay territory, so the same shape appears again in every other format in this category.
- geojsonGeoJSON Geometry — PointA one-feature FeatureCollection holding a single position, so a reader can be exercised on Point in isolation. Coordinates come from the Kestrel Bay territory, so the same shape appears again in every other format in this category.
