toJSON

Converts the geometry to a GeoJSON Feature object.

This method allows the geometry to be serialized to JSON and is automatically called by JSON.stringify().

geom.toJSON() is equivalent of calling toGeoJSON(geom, { flavor: 'extended', layout: 'XYZM' })

Returns

JSON_Feature<JSON_Geometry, P>

A GeoJSON Feature representation of this geometry

• toGeoJSON converts geometry to a GeoJSON Feature or a GeoJSON FeatureCollection object.

Examples

const geom = point([ 1, 2, 3 ]);
const geojson = geom.toJSON();
// {
//     type: 'Feature',
//     geometry: { type: 'Point', coordinates: [ 1, 2, 3 ] },
//     properties: null,
// }
const geojsonStr = JSON.stringify(geom);
// '{"type":"Feature","geometry":{"type":"Point","coordinates":[1,2,3]},"properties":null}'

const geom = point([ 1, 2, 3 ]); const geojson = geom.toJSON(); // { // type: 'Feature', // geometry: { type: 'Point', coordinates: [ 1, 2, 3 ] }, // properties: null, // } const geojsonStr = JSON.stringify(geom); // '{"type":"Feature","geometry":{"type":"Point","coordinates":[1,2,3]},"properties":null}'
