How to open rosbag files
The log data is in .bag format, the standard logging format for ROS. To simply view and play the data Foxglove Studio is the easiest solution. It works on Windows, Linux and Mac. Another popular option is MATLAB. The data can be imported, viewed and edited in MATLAB. If you are familiar with ROS C++ or python can be a good option too. Python also offers possibilities top open the rosbags without ROS, similarly to MATLAB. The postprocessed 3D pointcloud data is in .pcd (Point Cloud Data) file format, it is a common format used inside Point Cloud Library (PCL). Also pcd can be imported easily to MATLAB / python.
