Base Address Pune

Datalist address

Address 1 Bombay result distance between pune and bombay 200 Km

Address 1 Kolkota result distance between pune and kolkata 500 Km

 //*********DISTANCE AND DURATION**********************//
            var service = new google.maps.DistanceMatrixService();
            service.getDistanceMatrix({
                origins: [source],
                destinations: [destination],
                travelMode: google.maps.TravelMode.DRIVING,
                unitSystem: google.maps.UnitSystem.METRIC,
                avoidHighways: false,
                avoidTolls: false
            }, function (response, status) {
                if (status == google.maps.DistanceMatrixStatus.OK && response.rows[0].elements[0].status != "ZERO_RESULTS") {
                    var distance = response.rows[0].elements[0].distance.text;
                    var duration = response.rows[0].elements[0].duration.text;
                    var dvDistance = document.getElementById("dvDistance");
                    dvDistance.innerHTML = "";
                    dvDistance.innerHTML += "Distance: " + distance + "<br />";
                    dvDistance.innerHTML += "Duration:" + duration + "<br />";

                } else {
                    alert("Unable to find the distance via road.");
                }
