turf line-overlap module
npm install @spatial/line-overlapTakes any LineString or Polygon and returns the overlapping lines between both features.
- line1 ([Geometry][1] \| [Feature][2]<([LineString][3] \| [MultiLineString][4] \| [Polygon][5] \| [MultiPolygon][6])>) any LineString or Polygon
- line2 ([Geometry][1] \| [Feature][2]<([LineString][3] \| [MultiLineString][4] \| [Polygon][5] \| [MultiPolygon][6])>) any LineString or Polygon
- options [Object][7] Optional parameters (optional, default {})
- options.tolerance [number][8] Tolerance distance to match overlapping line segments (in kilometers) (optional, default 0)
``javascript
var line1 = turf.lineString([[115, -35], [125, -30], [135, -30], [145, -35]]);
var line2 = turf.lineString([[115, -25], [125, -30], [135, -30], [145, -25]]);
var overlapping = turf.lineOverlap(line1, line2);
//addToMap
var addToMap = [line1, line2, overlapping]
`
Returns [FeatureCollection][9]<[LineString][3]> lines(s) that are overlapping between both features
