Package Exports

turf-quantile

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 (turf-quantile) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

turf-quantile

Takes a set of features, a property name, and a set of percentiles and outputs a quantile array. This can be passed as a break array to the isolines function or the isobands function.

var quantile = require('turf-quantile')
var fs = require('fs')

var propertyName = 'elevation'
var percentiles = [10,30,40,60,80,90,99]

var pts = JSON.parse(fs.readFileSync('/path/to/pts.geojson'))

var quantiles = quantile(pts, propertyName, percentiles)
    
console.log(quantiles) // [ 12, 25, 29, 52, 76, 99, 143 ]
