摘要： As a critical reference for the management of fisheries production, fishing benefits calculation, and fishery resources survey, the statistics of vessel voyage can be readily available with the assistant of vessel monitoring system using Beidou satellite navigation. In this paper, a novel methodology has been presented to obtain the vessel voyage automatically using Beidou. The proposed approach firstly creates polygon object from land and islands that the departure and return ports located using GIS buffering method. After that, the distance between the vessel and the edge of the created buffer is regarded as the distance to coastline, the variation of which is utilized to determine the vessel voyage. We then extract the voyages automatically by analyzing the pattern of distance variation in various circumstances. The voyage information of six fishing vessel are extracted using the proposed method, and the result is then compared with the actual records of 43 voyage. The result of experiments is very promising, approximate 95.1% of the departure time are within 2 days, and about 95.2% of the return time are within 2 days, which has validated that the proposed method can provide accurate reference information for fishery analysis.
