Description

clusterEach

Parameters

NameTypeDescription
geojsonFeatureCollectionGeoJSON Features
propertystring | numberGeoJSON property key/value used to create clusters
callbackFunctiona method that takes (cluster, clusterValue, currentIndex)

Returns

    void

Examples

var geojson = turf.featureCollection([
turf.point([0, 0]),
turf.point([2, 4]),
turf.point([3, 6]),
turf.point([5, 1]),
turf.point([4, 2]),
]);

// Create a cluster using K-Means (adds `cluster` to GeoJSON properties)
var clustered = turf.clustersKmeans(geojson);

// Iterate over each cluster
turf.clusterEach(
clustered,
"cluster",
function (cluster, clusterValue, currentIndex) {
//= cluster
//= clusterValue
//= currentIndex
},
);

// Calculate the total number of clusters
var total = 0;
turf.clusterEach(clustered, "cluster", function () {
total++;
});

// Create an Array of all the values retrieved from the 'cluster' property
var values = [];
turf.clusterEach(clustered, "cluster", function (cluster, clusterValue) {
values.push(clusterValue);
});
