@koide3 @tranducthuan1 When input `rosservice call /hdl_graph_slam/save_map "resolution: 0.05 destination: '/home/whu/data/hdl_graph/map.pcd'" ` I have the same error: yaml.scanner.ScannerError: mapping values are not allowed here in "", line 1, column 29:...

@tranducthuan1 I have solved the problem. After `rviz -d hdl_graph_slam.rviz`, then execute two lines command `rosservice call /hdl_graph_slam/save_map "resolution: 0.05 destination: '/full_path_directory/map.pcd'"` with "\\".
