Merged center line map data

[mattangus]

Is there a full merged center line dataset available? Each frame only has annotations for what seems to be stated in the paper as ±30m from the vehicle. Is there a more "global" source that I can get center lines farther than this 30m range. A bonus for this data would be the connections between segments. I.e. centerline id 1 is connected to centerline id 2 and 3.

I can merge all of the frames together but there are some difficulties involved because the lines are truncated so determining their true end point could be an issue. The connections might also become an issue if the position of the connections are not exactly identical.

Hi, @mattangus. You can use the HDMap from the original dataset. So you can get the global map information, with non-truncated lane.
BTW, we have ±50m map in this OpenLane-V2 dataset.
