摘　　要：矢量地图数据在人类的社会、经济活动中发挥着不可替代的作用,许多行业如城市规划、环境保护、汽车导航、工程设计、资源勘察、土地管理、抢险救灾、观光旅游以及军事指挥等都离不开地图数据的支持。它具有易于更新、复制和分发等特点,同时,也方便了地图数据的非法复制、分发及伪造行为,它的版权保护问题日益引起人们的重视。分析了矢量地图数据的特点及可能的水印操作空间,总结了现有的矢量地图数据的水印算法及存在的问题,并指出了矢量地图数据数字水印需要进一步研究的问题。The vector map data have played an irreplaceable role in the social and economic activities. Many businesses, such as, urban-planning, environmental protection, vehicle navigation system, project design, resources exploration, land managing, rescue and disaster relief, traveling and military commanding, involved the support of vector map data. As digital data, the vector map data were easy to update, duplicate and distribute. At the same time, illegal duplication and distribution or forgery of the maps were also easy. Hence, the issue on the protection of their copyrights was drawn a great attention. The characteristics of map data and watermarking operation space were analyzed, existing algorithms and its problems were summarized, research directions and key issues in the field in future were proposed.
