toJSON

Examples

var exported = tree.toJSON()

Returns any export data as JSON object

fromJSON

fromJSON

Parameters

• json any import previously exported data

Examples

    {
      "type": "Feature",
      "geometry": {

}
tree.fromJSON(exported)

Returns RBush GeoJSON RBush

rbush

GeoJSON implementation of RBush spatial index.

Parameters

• maxEntries number defines the maximum number of entries in a tree node. 9 (used by default) is a reasonable choice for most applications. Higher value means faster insertion and slower search, and vice versa. (optional, default 9)

Examples

var geojsonRbush = require('geojson-rbush').default;
var tree = geojsonRbush();

Returns RBush GeoJSON RBush
