@turf/line-segment

lineSegment

Creates a FeatureCollection of 2-vertex LineString segments from a LineString, MultiLineString, MultiPolygon or Polygon.

Parameters

• geojson (FeatureCollection | Feature<(LineString | MultiLineString | MultiPolygon | Polygon)>) GeoJSON Polygon or LineString

Examples

var polygon = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Polygon",
    "coordinates": [[[-50, 5], [-40, -10], [-50, -10], [-40, 5], [-50, 5]]]
  }
}
var segments = turf.lineSegment(polygon);

//addToMap
var addToMap = [polygon, segments]

Returns FeatureCollection<LineString> 2-vertex line segments
