Leaflet.AlmostOver

This plugin allows to detect mouse click and overing events on lines, with a tolerance distance.

It is useful if paths are drawn with a very small weight, or for clicks detection on mobile devices, for which finger precision can be a problem.

Play with online demo.

It requires Leaflet.GeometryUtil.

Usage

    var map = L.map('map');
    ...
    var lines = L.geoJson(...);
    ...
    map.almostOver.addLayer(lines);

    map.on('almost:over', function (e) {
        alert('Almost clicked !');
    });
