多尺度空间关系相似性研究

如何快速、自动地实现多尺度地图自动综合结果质量评价,对提高空间数据质量、加快空间数据生产周期等具有重要意义.本文在综合考虑拓扑关系、方向关系和距离关系的基础上,基于SRM模型提出了基于面状目标的空间关系相似性的度量方法,为地图自动综合提供空间关系评价和维护的参考.

Research on spatial relation similarity in multi-scale maps

How to quickly and automatically evaluate the results quality of multi-scale automated map generalization is of great importance to improve the spatial data quality and speed up the production cycle.Based on the SRM model,a measurement method of spatial relation similarity among planar targets was proposed in the comprehensive consideration of topological,directional and distance relations,which could provide the reference to spatial relation evaluation and maintenance for automated map generalization.
