基于OpenLayers的金枪鱼延绳钓辅助生产分析系统

Auxiliary production analysis system of tuna longline fishing based on OpenLayers

金枪鱼作为一种高度洄游性鱼类,是国际渔业主要捕捞对象之一,其渔场变化受海洋环境变化影响大,因此分析海况与产量关系可以很好地辅助生产决策。从日本海况网站、远洋渔业综合服务平台下载数据到数据库,并导入公司渔获数据,然后基于OpenLayers控件实现海表温度、海面高度、次表层水温的多窗口协同浏览以及渔获数据的叠加。软件实现海图放大、缩小、移动等浏览操作,显示当天的海况、船位、渔获数据,可以翻页查看捕捞状况,在地图上点击船位能够显示该点的产量数据。软件为海况信息快速查询,不同时间产量对比提供便利,能够很好地辅助生产决策综合分析。

Tuna,a highly migratory fish,is one of the main fishing targets in the international fishery.Changes of fishing grounds are greatly influenced by changes of marine environment,so the analysis of the relationship between sea conditions and the yield can be a good auxiliary production decision. In this paper,the data came from the Japanese sea state web site and the ocean fishing comprehensive service platform was downloaded to the database. Company＇ s catch data could be automatically imported to the database. The multi-window cooperative browsing of sea surface temperature,sea surface height and subsurface water temperature is realized by OpenLayers control. And the catch data can be over layered. The software realizes the navigation of the sea map,such as zoom in,zoom out,shift and so on. It shows sea conditions,vessel positions and catch data of the day. It can page back and forth to check fishing. Clicking on the map can show the catch of that position. The system provides a quick query for sea condition information and is convenient for output comparison of different time. It can be a good comprehensive analysis of auxiliary production decision.
