Looking at my employers network... We know the GPS coordinates for each BGP next-hop in the network, and traffic is sampled on ingress at the edge of the network and reported to pmacct (*flow), which also receives a RR-style BGP feed for correlation. We can know where (geographically) a packet enters the network, where it leaves the network and to what address family it belongs. However, this would be just one network's (biased) view on things.
