Important Navigation Routes defining boundary of policy PS2 in the East Inshore and East Offshore marine plans Web Feature Service (WFS)

The data to define the extent of policy PS2 in the East Inshore and East Offshore marine plans was based on identification of important navigation routes. Important navigation routes are areas defined as being where there are more than 1,000 vessel transits per year. Within these defined areas, important navigation routes are identified by taking the 90th percentile from the median line of all shipping traffic. Important navigation routes were then cropped to remove (1) routes passing through Round 3 offshore wind zones and (2) parts of routes within port and harbour jurisdictions. This dataset was produced by Anatec Ltd using Anatec's ShipRoutes database to identify areas of high shipping density and vessel tracks in the East Inshore and East Offshore plan areas. This database uses AIS data (Automatic Identification System) and modelling to define routes本数据集用于明确东部近岸与东部远海海洋规划中政策PS2的适用范围，其构建基于重要航行航线的识别工作。重要航行航线指年船舶通行量超过1000艘次的水域。在上述划定的水域范围内，通过提取所有航运交通流中线的90百分位值，完成重要航行航线的识别。随后对识别得到的重要航行航线进行裁剪处理，以剔除两类区域内的航线：（1）穿越第三轮海上风电区域的航线；（2）位于港口港区管辖范围内的航线片段。本数据集由Anatec Ltd依托其ShipRoutes数据库开发完成，该数据库用于识别东部近岸与东部远海规划区域内的高航运密度水域及船舶航迹。该数据库依托AIS（Automatic Identification System，自动识别系统）数据与建模手段完成航线划定。
