This is probably a dumb question.

I am working with the Kitti dataset. I am trying to express the content of the topic /kitti/oxts/gps/fix (NavSatFix - lat, long, alt) in the reference world reference system of Tf (x, y, z).

Do you know a way to do it? Thanks

Hi @Filippo Grazioli,

Have you considered the robot_localization package and its navsat_transform_node?

My personal solution was the following:

a) transform the initial GPS position (lat, long, alt) to an ECEF point - let's name this O;

b) center a ENU reference system in O;

c) express all other GPS positions (lat, long, alt) w.r.t. the ENU reference system centred in O.
