Identifying roles of fishing ports using multi-source data aggregation

Managing and maintaining fishing ports is crucial for fishing activities. With the lack of budget and labor force, some fishing ports face the brink of being shut down. A first choice for demolishing would be fishing ports with low utilization, but this does not mean the port is totally useless. When severe weather condition, i.e., typhoons, is in the proximity of the coastal line, offshore fishing vessels will return to dock in ports for safety. When major ports are fully docked, some of the minor ports or less active ports will be chosen as the haven. These ports are seldom used and lowly utilized, but should still be maintained for safety issues as they serve as a sanctuary for extreme weather conditions. This research uses big data aggregation approach to identify haven ports by processing fishing vessel states using collected voy­age data recorder (VDR) records and correlates this information with the typhoon information data source.
