随着网络地图的发展，人们不再满足于固定的、有限比例尺的地图服务，而是希望获得个性化的、任意比例尺的地图数据。连续地图综合技术可用于生成任意比例尺的地图数据。提出了一种基于形状上下文匹配和分层内插的线状地图要素连续概化方法(SCM-HI)。更具体地说，通过形状上下文来定量描述形状特征，并基于卡方方法度量形状相似度；然后，采用骨架和细节两级内插来生成中间曲线的几何形状。该方法的主要贡献包括：(1)在形状匹配中利用了矢量曲线的几何和空间结构；(2)通过分层内插，使得中间曲线的主形状结构尽可能刚性，局部几何细节尽可能地渐进和光滑。实验表明，该方法能够产生合理的变形效果，从而为线状地图要素的连续综合提供了一种稳健的方法。
With the development of web maps, people are no longer satisfied with fixed and limited scale map services but want to obtain personalized and arbitrary scale map data. Continuous map generalization technology can be used to generate arbitrary scale map data. This paper proposes a morphing method for continuously generalizing linear map features using shape context matching and hierarchical interpolation (SCM-HI). More specifically, shape characteristics are quantitatively described by shape context on which shape similarity is measured based on a chi-square method; then, two levels of interpolation, skeleton and detail interpolations, are employed to generate the geometry of intermediate curves. The main contributions of our approach include (1) exploiting both the geometry and spatial structure of a vector curve in shape matching by using shape context, and (2) preserving both the main shape structure as-rigid-as-possible and local geometric details as gradual and smooth as possible for intermediate curves by hierarchical interpolation. Experiments show that our method generates plausible morphing effects and can thus serve as a robust approach for continuous generalization of linear map features.
