@turf/line-overlap

lineOverlap

Takes any LineString or Polygon and returns the overlapping lines between both features.

Parameters

• line1 Feature<(LineString | MultiLineString | Polygon | MultiPolygon)> any LineString or Polygon
• line2 Feature<(LineString | MultiLineString | Polygon | MultiPolygon)> any LineString or Polygon

Examples

var line1 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "LineString",
    "coordinates": [[115, -35], [125, -30], [135, -30], [145, -35]
    ]
  }
}
var line2 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "LineString",
    "coordinates": [[115, -25], [125, -30], [135, -30], [145, -25]
    ]
  }
}
var overlapping = turf.lineOverlap(line1, line2);
//= overlapping

Returns FeatureCollection<LineString> lines(s) that are overlapping between both features
