 1. **Rich sensory information** including vision, lidar, IMU, GNSS,event, thermal-infrared images and so on
 2. **Various scenarios** in real-world environments including lifts, streets, rooms, halls and so on.
 3. Our dataset brings **great challenge** to existing cutting-edge SLAM algorithms including [LIO-SAM](https://github.com/TixiaoShan/LIO-SAM) and [ORB-SLAM3](https://github.com/UZ-SLAMLab/ORB_SLAM3). If your proposed algorihm outperforms these SOTA systems on our benchmark, your paper will be much more convincing and valuable.
