How to get the initial world frame origin?

[zhimengf]

According to the arxiv paper, the world frame is ENU coordinate system. All vehicle frames are relative to the world frame. Is there any place to get the exact location of the origin of the world frame: (longitude, latitude, altitude)? I ask this because I want to convert all vehicle frames to absolute values rather than relative. Thanks!

If you are referring to the motion dataset, unfortunately we are not able to provide absolute world coordinates at this time.
