Map is not corrected with GPS odometry

[mintrhey]

Hello!

First of all, thank you so much for this repo, it help me so much!

So, I have a question, I tried the park_dataset.bag and the map eventually corrected with the odometry from gps, however, when I tried to do it with my dataset, it doesn't.

As you can see in the photo, the global path and the odometry/gps does not merge. What has to be wrong? I hope you or anyone can help. Thank you!

Regards,
Lucy
