Description

Autoware uses an extended version of the Lanelet2 format as the input map to run. Additionally, there are a few additional requirements that must be met by the map to enable the correct behavior of Autoware when driving on them. This task focuses in ensuring the converted map meets such requirements.

Purpose

To enable Autoware to behave correctly when driving on converted maps.

Possible approaches

• Summarize the Autoware map requirements → Done, available here
• Filter out requirements that are not applicable for virtual maps → Done, available on link above
• Set a priority level to each requirement based on the relevance for SSv2 and Autoware → Done, available on link above
• Check if each HIGH priority requirement is met by the conversion tool, and adapt the tool if it is not

Definition of done

The HIGH priority requirements are confirmed to be met by the map converter tool.
