摘要
本文从数字水印的本质出发，分析了矢量地图数字水印加载的三个要求以及传统水印存在的问题；然后，基于地图制图综合的定义和基本方法，根据地图制图综合成果评判标准中存在的模糊区间，即允许存在两种或多种不同的制图综合结果，提出了利用不同制图综合结果作为加载矢量地图数字水印的新思路，并把它叫做制图综合水印；最后，本文对制图综合水印的特点进行了分析，提出了其加载原则。
At first, this paper analyzes three requirements of loading vector map digital watermark and the limitations of traditional watermark. Then, a new thought of loading vector map digital watermark on utilizing cartographic generalization, which is based on cartographic generalization achievements, is presented and named cartographic generalization watermark. At the end of this paper, the characteristics of cartographic generalization watermark are discussed, and the loading principles are proposed.
