Hi everyone, I am using 2 instances of robot_localization pkg, and Rtabmap SLAM as map provider. it is said that the output of navsat_transform node will transform geographic coordinates (latitude and longitude) into the robot’ world frame. Now I want to know, how can I calculate the distance between two GPS coordinates? as I checked odometry/gps again provides lat and values! Will any topic provide this to me?

Thanks

I am not sure I understand how you want to get this difference from a topic. But to calculate the distance between 2 GPS points you could use a Python package like geopy

As shown in the repo, a simple example:

from geopy.distance import geodesic
newport_ri = (41.49008, -71.312796)
cleveland_oh = (41.499498, -81.695391)
print(geodesic(newport_ri, cleveland_oh).miles)
538.390445368
