Limulator aims at generating LiDAR data as per user specifications. The software facilitates user to create terrain of his/her choice using available tools. User has option for selection of either generic sensor or commercially available sensors and can set their parameters accordingly. The simulator generates LiDAR data similar to a real LiDAR sensor for further display and analysis. The Limulator can be useful to instructors and students to generate variety of LiDAR data for experimentation. The readily available accurate ground truth and the ability to produce LiDAR data with different specifications make this software also suitable for algorithm testing (e.g. information extraction) and research. Further, it can be useful in flight planning. Being cross platform software, it can be installed on any operating system.
