Dataset lacks the absolute location

[BrusonX]

Thanks for your excellent dataset.
I want to do some experiments on your excellent dataset for Place Recognition but I have a question: the submap in the dataset doesn't have absolute location because only relative poses of submaps are given, long-term information of multiple trajectories can't be recognized. So I ask that if you can release the GPS or absolute location of every submaps in every track? Thank you!

I encountered the same problem where the trajectories exported from each submap cannot be assembled into a global map, which are most likely poses in a local coordinate system.
