Country contours Europe

Polygons from countries around the North Sea. Note: The data of the coastline were supplied by Hydrografie in WGS 1984. Because there is a transformation problem in ArcGIS to get well projected from WGS 1984 to ED50, the quality of this dataset is not guaranteed. We are now looking at how to solve this problem.北海周边国家的多边形地理数据。注：海岸线数据由Hydrografie提供，采用WGS 1984坐标系。由于在ArcGIS软件中，将该数据从WGS 1984坐标系投影转换至ED50坐标系时存在转换异常，本数据集的质量无法得到保证。目前我们正着手研究解决该问题的方案。
