gps waypoints are not shown in mapviz

edit

Thanks, @osilva, up to this step, everything is fine, I want to have GPS waypoints that are recorded as a goal, be shown in mapviz, i have attached the pic in my question.

In the source code, you can see the node subscribes to three topics I think only /outdoor_waypoint_nav/gps/filtered is relevant:

Source code: https://github.com/ArghyaChatterjee/g...

 //Subscribe to topics
    ros::Subscriber sub_gps_raw = n.subscribe("/navsat/fix", 100, raw_gps_CB);
    ros::Subscriber sub_gps_filtered = n.subscribe("/outdoor_waypoint_nav/gps/filtered", 100, filtered_gps_CB);
        ros::Subscriber sub_joy = n.subscribe("/joy_teleop/joy", 100, joy_CB);

I guess you could do the same publish to this topic.

this code only record and save the GPS/ filtered points:

ROS_INFO("You have collected another waypoint cluster!");
ROS_INFO("Press %s button to collect and store another waypoint.", collect_button_sym.c_str());
ROS_INFO("Press %s button to end waypoint collection.", end_button_sym.c_str());

I donot know why the named this file, ploting GPS points!?

Take a look at this launch file:

You also need to work with parameter server send waypoints.
