Package Exports
- geojson-rbush
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (geojson-rbush) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

GeoJSON RBush
GeoJSON implementation of RBush — a high-performance JavaScript R-tree-based 2D spatial index for points and rectangles.

rbush
GeoJSON implementation of RBush spatial index.
Parameters
maxEntriesnumber? 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, default9)
Examples
var rbush = require('geojson-rbush')
var tree = rbush()Returns RBush GeoJSON RBush
insert
Parameters
featureFeature<any> insert single GeoJSON Feature
Examples
var polygon = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-78, 41], [-67, 41], [-67, 48], [-78, 48], [-78, 41]]]
}
}
tree.insert(polygon)Returns RBush GeoJSON RBush
remove
Parameters
featureFeature<any> remove single GeoJSON Feature
Examples
var polygon = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-78, 41], [-67, 41], [-67, 48], [-78, 48], [-78, 41]]]
}
}
tree.remove(polygon)Returns RBush GeoJSON RBush
load
Parameters
featuresFeatureCollection<any> load entire GeoJSON FeatureCollection
Examples
var polygons = {
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-78, 41], [-67, 41], [-67, 48], [-78, 48], [-78, 41]]]
}
},
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-93, 32], [-83, 32], [-83, 39], [-93, 39], [-93, 32]]]
}
}
]
}
tree.load(polygons)Returns RBush GeoJSON RBush
search
Parameters
geojson(FeatureCollection | Feature<any>) search with GeoJSON
Examples
var polygon = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-78, 41], [-67, 41], [-67, 48], [-78, 48], [-78, 41]]]
}
}
tree.search(polygon)Returns FeatureCollection<any> all features that intersects with the given GeoJSON.
collides
Parameters
geojson(FeatureCollection | Feature<any>) collides with GeoJSON
Examples
var polygon = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[[-78, 41], [-67, 41], [-67, 48], [-78, 48], [-78, 41]]]
}
}
tree.collides(polygon)Returns boolean true if there are any items intersecting the given GeoJSON, otherwise false.
all
Examples
tree.all()
//=FeatureCollectionReturns FeatureCollection<any> all the features in RBush
