多尺度变换中建筑群空间相似度计算模型

针对建筑群自动综合结果质量评价问题,该文提出一种建筑群多尺度表达中空间相似度计算模型。从地图综合质量评价的角度,立足地图综合的3个约束,即图形约束、拓扑约束、结构约束,分别计算了图形相似度、拓扑相似度、结构相似度,并对以上各相似度作了适当的权重分配,计算建筑群目标的整体相似度。最后,通过实验验证了本文相似度计算方法的正确性、可行性。

A spatial similarity computation model between building groups in multi-scale map space

Aiming at the quality evaluation of automated cartographical generalizations for building group,a model of spatial similarity calculations was proposed which was used in multi-scale representation of building group.From the perspective of quality evaluation of cartographic generalization,graphic similarity,topological similarity and structural similarity were calculated respectively based on three constrains of map generalization containing graphic constrain,topological constrain and structural constrain.Weight was distributed reasonably to each of the similarity and overall similarity of building group was calculated.Finally,the experiments showed that the method proposed in this paper about similarity calculation was correct and feasible.
