For MaiCity dataset, sequence 01 and 02 are sampled from the same 3D model (the one inside the gt_models folder) with different beam numbers. But sequence 00 is sampled from another 3D model (which is not provided).
We used sequence 01 for the reconstruction evaluation with the ground truth point cloud generated from the much denser sequence 02. To also take the scene completion quality into account, we combine that point cloud with the ground surface of the original 3D model to generate the gt_map_pc_mai.ply. The reason why we do not directly use the original 3D model is that it's not watertight and has multiple layers inside the wall and under the ground (you may open gt_models/mai_city_block.ply to check).
For more details regarding the dataset, you may refer to the original paper section IV A and also the README.md file under the dataset folder.
I hope I have answered your question.
