Description

• When bag file of elevation map is broken, elevation_map_loader node cannot load it and dies.
• So if elevation_map_loader node cannot load broken bag file, removing broken bag file and create elevation map.

Review Procedure

Follow the steps below to ensure that the elevation map is generated even if there is broken bag file in /install/elevation_map_loader/share/elevation_map_loader/data/elevation_maps.

1. Create elevation map.
2. Check if there is .db3 file in /install/elevation_map_loader/share/elevation_map_loader/data/elevation_maps/<MAP_HASH>/. <MAP_HASH> depends on pointcloud map you used to create elevation_map. For example, /install/elevation_map_loader/share/elevation_map_loader/data/elevation_maps/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee_0.db3 is that bag file.
3. Remove this file and create empty file with the same name as the removed bag file. For example,

rm -rf /install/elevation_map_loader/share/elevation_map_loader/data/elevation_maps/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee_0.db3
touch /install/elevation_map_loader/share/elevation_map_loader/data/elevation_maps/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee/2b0fe3948d486f048177b826fbba046d468956e51b25e9916feef02b0aeffeee_0.db3

4. Check if the broken bag file is removed and the elevation map is generated again.
