| 中文摘要 | 分析了道路网多尺度抽象表达的影响因素及由此造成的多种抽象表达模式共存的现象,指出该问题的本质是一个如何界定路网要素多尺度表达本体的问题,提出了基于“自然法则”的路网要素多尺度表达的本体解决方案.从界定“自然法则”的路网要素多尺度最小制图表达目标出发,剖析了基于自然法则抽象和量化各尺度区间下多尺度表达实体类、几何抽象类型、多尺度表达间语义关系的本体解决策略,为路网多尺度数据模型的构建提炼出多尺度实体和关系的客观概念视图.; The key factors affecting multi-scale representations from road features were analyzed in this paper.It is considered that multiple abstraction and representation schemas are caused by inconsistent conceptual cognition,abstractions and representation rules,which is in nature an ontological problem on ascertaining multi-scale entities and relations from multi-scale representations.So,an ontological solution based on the natural principle was provided to accommodate the inconsistent conceptual cognition,in which cartographical natural rules served as a basic and general guideline in modeling multi-scale representation.Based on the strategies,multi-scale objective abstractions and quantitative representations were implemented in the following steps,namely smallest visible object(SVO) measurement,geometry type abstraction,and semantic relation investigation.Thus it is followed by a detailed description of multi-scale geometrical abstract type and entity hierarchy during road network multi-scale conceptual views,as well as the hierarchical semantic relations at both the feature class level and representation level,which provides a unified and objective multi-scale conceptual view for multi-scale road network modeling.; 国家自然科学基金项目(40471090) |
