DBTR — Sea Coast Line — (COS_GLI)

Represents portions of sea areas, adjacent to the sea coast line, the acquisition of which is significant (e.g. due to the presence of defence works or other artifacts, islands or rocks, production facilities, navigation equipment, etc.). Islands, rocks and unpalified works “hole” the sea area.本数据集涵盖毗邻海岸线的部分海域，此类海域的采集工作具备重要意义——例如该区域内存在防御工事、其他人工构筑物、岛屿或岩礁、生产设施、导航设备等场景。岛屿、岩礁以及未整治的人工设施会在该海域中形成"孔洞"状分割。
