Currently i am using routeboxer.js to get the different boxes within that route. everything works perfactly in routeboxer any i am getting 4  longitude and latitude 

boxes[i].getNorthEast().lat() + ',' + boxes[i].getNorthEast().lng()

boxes[i].getSouthWest().lat() + ',' + boxes[i].getNorthEast().lng()

boxes[i].getSouthWest().lat() + ',' + boxes[i].getSouthWest().lng()

boxes[i].getNorthEast().lat() + ',' + boxes[i].getSouthWest().lng()
