Islands, Lake Victoria, Vector Polyline, ~2015 Reference Information and Units: Projected Coordinate System: Africa Lambert Conformal Conic ESRI:102024 (https://epsg.io/102024) GCS: GCS_WGS_1984 File Naming Convention: LV_Islands_Line.shp Data Origin: Created from using Shoreline data that was created from manual digitization from open-source imagery Data Development: This data was created by extracting all islands from the shoreline poly shapefile by using a combination or Erase, Explode, and delete to leave only internal LV Islands. Next the area of each island was calculated. These are the island polygons. Finally the polygons were converted to lines to form the island lines
维多利亚湖岛屿矢量折线（Vector Polyline）数据集，约2015年
参考信息与参数单位：投影坐标系（Projected Coordinate System）为非洲兰伯特等角圆锥投影（Africa Lambert Conformal Conic），ESRI代码：102024（访问地址：https://epsg.io/102024）；地理坐标系（GCS）为GCS_WGS_1984
文件命名规范：LV_Islands_Line.shp
数据来源：基于开源影像人工数字化生成的岸线数据制作所得
数据开发流程：首先通过擦除（Erase）、多部件拆分（Explode）与删除操作的组合处理，从岸线多边形形状文件中提取所有岛屿要素，仅保留维多利亚湖内部岛屿多边形；随后计算每个岛屿的面积；最终将岛屿多边形转换为折线，从而形成本岛屿矢量折线数据集
