Hi,
I am trying to implement autonomous navigation based on gps on a real robot for outdoor environment like a park/open filed. I follow the extra class and the rosject provided by the construct titled " How to use GPS to do autonomous robot navigation" and I read that you need to pass an empty map to the map server which is large enough to cover the whole area you want the robot to move on and I want to know how to obtain/create the .pgm image file of for such an environment ?
I understand that both the .pgm and .yaml files are automatically created my map server when saving a map produced by using packaged like gmapping but in my case the outdoor environment is a park/open field.
Can you please guide me ?
Regards,
Abhijit
