Does it mean that we could use this package to divide the output from bag2lanelet (which is a single lanelet) into multiple connected pieces and directly handled by Autoware?

@Owen-Liuyuxuan, this tool splits a single Lanelet2 file into multiple Lanelet2 files.

I never use the bag2lanelet package but since the input of our tool is single lanelet2 file, it should work with output of bag2lanelet.

Additionally, we are currently working on implementing dynamic lanelet2 loading in Autoware, and it's under review. You can check the PR for more details on the dynamic lanelet2 loading task.
