Fishing effort, measured in hours of inferred fishing activity. Each asset is the effort for a given flag state and day, with one band for the fishing activity of each gear type.

See sample Earth Engine scripts. Also see the main GFW site for program information, fully interactive visualization maps, and impacts.

捕捞强度,以推断的捕捞活动小时数衡量。每个资产是一个给定的旗帜状态和一天的努力,每个齿轮类型的捕捞活动有一个带子。

参见地球引擎脚本样本。也可参见GFW的主网站,了解项目信息、完全互动的可视化地图和影响。
