map edit and save

[vusdo]

I want to edit and save the map through the draw.html sample. How can you implement it?

Thank You..

One way of implementing it is to record the

1. polygon points (these would naturally be saved as points with respect to the map frame)
2. pass these points over to ROS using some sort of service call such as:

  request = new ROSLIB.ServiceRequest({
        polygon_points: JSON.stringify(points)
        above_occupied_thresh: true
    });
    
    edit_map.callService(request, function (result) {
        if (result.result) {
        console.log("Service successfully called")
        }
    });

3. On the ROS side receive the service topic, and set all pixels within these points to be occupied if above_occupied_thresh is true and set the points to be unoccupied if above_occupied_thresh is set to false
