| 摘 要： | 为了满足人们获取室内空间信息时多层次的认知需求,从室内空间的特点出发,以商城为例,对室内要素的分类分级体系进行梳理,在此基础上探讨兴趣点(point of inte-rest,POI)多尺度表达的符号模型;结合地图比例尺和用户需求设计了一套易于理解又能多层次表征要素信息的室内地图POI符号系统,并通过典型案例对其可行性进行制图实践检验。实践结果表明,所提出的多尺度POI符号化方案具有可行性,设计的符号集可以广泛运用到其他商城中,该思想可以运用于其他类型的室内地图。

| Abstract: | In order to meet the multi-level cognitive demands when acquiring indoor space information, we take shopping mall as an example to sort out the classification and gradation of indoor elements based on the characteristics of indoor space. On this basis, we discuss the symbol model of POI multi-scale expression, and combine the map scale and the demands of users to design an indoor map POI symbol system which is easy to understand and can represent the element information at different levels. Its feasibility is tested through typical cases. The practice shows that the proposed multi-scale POI symbolization scheme is feasible, and the designed symbols set can be used in other malls, and the idea can be applied to other types of indoor maps. |
