L.GeoJson

GeoJson

Represents a GeoJSON object or an array of GeoJSON objects. Allows you to parse GeoJSON data and display it on the map. Extends FeatureGroup.

L.geoJson(data, {
	style: function (feature) {
		return {color: feature.properties.color};
	},
	onEachFeature: function (feature, layer) {
		layer.bindPopup(feature.properties.description);
	}
}).addTo(map);

Each feature layer created by it gets a feature property that links to the GeoJSON feature data the layer was created from (so that you can access its properties later).

Creation

Factory	Description
`L.geoJson( <Object> geojson?, <GeoJSON options> options? )`	Creates a GeoJSON layer. Optionally accepts an object in GeoJSON format to display on the map (you can alternatively add it later with `addData` method) and an options object.

Options

Option	Description
`pointToLayer( <GeoJSON> featureData, <LatLng> latlng )`	Function that will be used for creating layers for GeoJSON points (if not specified, simple markers will be created).
`style( <GeoJSON> featureData )`	Function that will be used to get style options for vector layers created for GeoJSON features.
`onEachFeature( <GeoJSON> featureData, <ILayer> layer )`	Function that will be called on each created feature layer. Useful for attaching events and popups to features.
`filter( <GeoJSON> featureData, <ILayer> layer )`	Function that will be used to decide whether to show a feature or not.
`coordsToLatLng( <Array> coords )`	Function that will be used for converting GeoJSON coordinates to LatLng points (if not specified, coords will be assumed to be WGS84 — standard `[longitude, latitude]` values in degrees).

Additionally accepts all Path options for polylines and polygons.

Methods

Method	Returns	Description
`addData( <GeoJSON> data )`	`this`	Adds a GeoJSON object to the layer.
`setStyle( <Function> style )`	`this`	Changes styles of GeoJSON vector layers with the given style function.
`resetStyle( <Path> layer )`	`this`	Resets the given vector layer's style to the original GeoJSON style, useful for resetting style after hover events.

Static methods

Method	Returns	Description
`geometryToLayer( <GeoJSON> featureData, <Function> pointToLayer? )`	`ILayer`	Creates a layer from a given GeoJSON feature.
`coordsToLatLng( <Array> coords, <Boolean> reverse? )`	`LatLng`	Creates a LatLng object from an array of 2 numbers (latitude, longitude) used in GeoJSON for points. If `reverse` is set to `true`, the numbers will be interpreted as (longitude, latitude).
`coordsToLatLngs( <Array> coords, <Number> levelsDeep?, <Boolean> reverse? )`	`Array`	Creates a multidimensional array of LatLng objects from a GeoJSON coordinates array. `levelsDeep` specifies the nesting level (0 is for an array of points, 1 for an array of arrays of points, etc., 0 by default). If `reverse` is set to `true`, the numbers will be interpreted as (longitude, latitude).
