geojson
What is a .geojson file?
application/geo+json
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 a .geojson file
Use an example GeoJSON file to test geometry parsing, coordinate handling, and mapping libraries or GIS pipelines that render or analyze spatial features.

- GeoJSON SampleA GeoJSON FeatureCollection with a point, a line, and a polygon, for testing map tools and geo importers.
- World Cities (40 points, GeoJSON)The same 40 world cities as a GeoJSON FeatureCollection of Points (longitude, latitude order per RFC 7946), each with name, country, and population properties. The mapping twin of the CSV, for testing GeoJSON parsers and map renderers.
- Kestrel Bay Territory: Master GeoJSON (14 features)The master dataset for this category: five towns, three roads, three parcels (one with a courtyard hole), a lake with an island, a buoy MultiPoint and the county boundary, as an RFC 7946 FeatureCollection. Kestrel Bay County is invented: open ocean at 47 N / 12.5 W, matching no real place, settlement, road or parcel.
- Kestrel Bay Territory: Minified GeoJSONThe same 14 features with every optional byte of whitespace removed. Pair it with the pretty-printed master to test that a parser's output is whitespace-independent and that a formatter round-trips without reordering members.
- GeoJSON 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.
- GeoJSON 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.
- GeoJSON 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.
- GeoJSON Geometry: MultiLineStringA one-feature FeatureCollection holding all three roads as one geometry, so a reader can be exercised on MultiLineString in isolation. Coordinates come from the Kestrel Bay territory, so the same shape appears again in every other format in this category.
