Field Reference

typerequiredstringAlways 'Feature' for a single feature object

geometry.typerequiredstringGeometry kind: Point, LineString, Polygon, MultiPolygon, etc.

geometry.coordinatesrequiredarrayCoordinates as [longitude, latitude] — note the order is lon, lat

propertiesrequiredobject | nullArbitrary attributes for the feature; may be null but the key must exist

Variants

FeatureCollectionMultiple features wrapped in a collection — the most common top-level GeoJSON.

Frequently Asked Questions

GeoJSON (RFC 7946) mandates [longitude, latitude] order to match the x, y convention. This trips many people up because mapping libraries like Leaflet use [lat, lng] in their APIs. Always double-check the order when converting between formats.

A Geometry is just the shape (type + coordinates). A Feature wraps a geometry with 'properties' (attributes like name or category) and an optional id. A FeatureCollection holds many Features. Most apps work with Features so they can attach metadata.

Yes. For Polygon and MultiPolygon, each linear ring must start and end with the same coordinate pair. Many tools tolerate unclosed rings, but per the spec they should be explicitly closed.
