    Hello Madhulika,

    Although 'export' is very ambiguous, here's a way to console log the drawn polygon as 'geojson' string:-

    map.on(‘draw:created’, function (e) {
    var type = e.layerType,
    layer = e.layer;

    if (type === ‘polygon’) {
        // structure the geojson object
        var geojson = {};
        geojson[‘type’] = ‘Feature’;
        geojson[‘geometry’] = {};
        geojson[‘geometry’][‘type’] = “Polygon”;

        // export the coordinates from the layer
        coordinates = [];
        latlngs = layer.getLatLngs();
        for (var i = 0; i < latlngs.length; i++) {
            coordinates.push([latlngs[i].lng, latlngs[i].lat])
        }

        // push the coordinates to the json geometry
        geojson[‘geometry’][‘coordinates’] = [coordinates];

        // Finally, show the poly as a geojson object in the console
        console.log(JSON.stringify(geojson));
    }

    drawnItems.addLayer(layer);
});

    I hope this will help.

    thanks

    Hi,

    I have found this code online, try this and let me know -

    map.on(‘draw:created’, function (e) {
    var type = e.layerType,
    layer = e.layer;

    if (type === ‘polygon’) {
        // here you got the polygon points
        var points = layer._latlngs;

        // here you can get it in geojson format
        var geojson = layer.toGeoJSON();
    }
    // here you add it to a layer to display it in the map
    drawnItems.addLayer(layer);
});

    Hope this helps.
