how can i generated a 2D map using Zed with ROS2? I can only see 3D Map when mapping mode is enabled. Because I will use this 2dmap for Nav2

Hi @AddyPete
we are working on a ZED SDK module to provide this feature that will be released in the next few months.
Meanwhile, you can use STVL layer, Voxel Layer, Obstacle layer to convert point cloud messages into local and global cost maps.
Here’s a full list of available plugins that you can use: Navigation Plugins — Navigation 2 1.0.0 documentation

okay thanks, so I don’t need to use SLAM toolbox for mapping right? If yes, does it publish map->odom transformation?
Hello I just installed STVL Nav2 plugin. But I got error when running nav2.

The nav2 nodes succesfully launched but it has error in this part:
