Intersection Point Of Two Lines In Leaflet

I want to get the intersection point of two polylines in leaflet. I have two lines as given below :- var latlng1 = L.latLng(-7.9375, 4.46354); var latlng2 = L.latLng(-7.96875, 16

Solution 1:

If you don't want to code all the logic, there is a small and easy to use library called Turf that provides several geoprocessing algorithms. You can even use just one of the algorithms mostly independent of the rest of the library.

The lineIntersects module does exactly what you want.

var intersection = turf.lineIntersect(polyline1.toGeoJSON(), polyline2.toGeoJSON());
var intersectionCoord = intersection.features[0].geometry.coordinates;

Also you can check the source code of the module for inspiration.
