 # Using divided pointcloud map
 
-Divided pointcloud map is necessary when handling large pointcloud map, in which case Autoware may not be capable of sending the whole map via ROS 2 topic or loading the whole map into memory. By using the pre-divided map, Autoware will dynamically load the pointcloud map according to the vehicle's position. For specific format definition of the divided map, please refer to [Map component design page](https://autowarefoundation.github.io/autoware-documentation/main/design/autoware-architecture/map/).
