Flatten MultiPoint, MultiPolygon, MultiLineString, and GeometryCollection geometries in GeoJSON files into simple non-complex geometries.
If a FeatureCollection is passed in, a FeatureCollection is returned. If a single Feature is passed in, an array of Features is returned.
npm install --save geojson-flatten
Or download geojson-flatten.js for non-browserify usage.
let flatten = require('geojson-flatten');
flattened = flatten(geojsonObject);
