 This package is built on top of the ROS ecosystem. You can start building a map with a pose graph constructed by [hdl_graph_slam](https://github.com/koide3/hdl_graph_slam) or odometry data generated by any ROS packages, such as [LeGO-LOAM](https://github.com/RobustFieldAutonomyLab/LeGO-LOAM). If you are interested in a ROS-independent cross platform version (Ubuntu/Windows), see [here](https://github.com/koide3/interactive_slam/wiki/Closed-source-version).
