Light Detection and Ranging (LIDAR) sensors are nowadays widely used for multiple applications such as autonomous driving, wind estimation and robots, however their use in airports has not yet been fully explored. Nevertheless, LIDAR sensors are decreasing in cost, and there are detection algorithms that could be useful in small airports. We present a system to visualize and detect aircraft in small airfields. The system enables an interactive calibration of the algorithm, and exploration of the results. The system has proven useful for the detection and positioning of airplanes in the ENVISION Sesar project.
