Abstract: This application relates to an apparatus for tracking location using a control platform of a small buoy for simulating marine pollutants, in which at least one small observation buoy floats on the ocean, and a relay buoy collects location information from the observation buoy and provides the collected location information to a weather information management server. The apparatus may include at least one observation buoy and a relay buoy, the observation buoy including a GPS receiver which receives a signal transmitted from a GPS satellite and generate location information. The apparatus may also include a communicator performing wireless transmission and reception of signals with the relay buoy, and a power source providing driving power to the GPS receiver and the communicator. The relay buoy may receive location information from the at least one observation buoy and provide the received location information to a weather information management server.

Abstract: A method for detecting a shipwrecked vessel and drown victims by using an aerial hyperspectral image, according to the present invention, comprises the steps of: (a) allowing an image reception unit to receive an observed aerial hyperspectral image, check whether the received aerial hyperspectral image is suitable for detection analysis, and extract observation information, and location information and a reflectance value for each pixel with respect to the detected shipwrecked vessel and drown victims; (b) allowing an image analysis unit to analyze spectral characteristic similarity between a spectral reflection value of a target object and an observed reflection value by using pre-constructed spectral library information and extract constituent materials and an occupation ratio for each pixel of the hyperspectral image, thereby classifying a detection result; and (c) allowing an image visualization unit to display the received hyperspectral image, locations of the detected shipwrecked vessel and drown victims, and detailed information of the detection result.
