Recover GPS data from pbstream #1831

Open mtlazaro opened 3 years ago

mtlazaro commented 3 years ago

Hi,

I would like to recover the GPS position associated to each node in the graph, so I could have a correspondence between map coordinates and GPS coordinates.

Is this information stored in the resulting pbstream and how could I recover this data? If not, could someone point me how could I do this? Maybe checking the timestamps from nodes and processing the bag separately.. but I don't know if timestamps are stored either.
