摘要
为了探索全空间信息系统空间认知的规律,使全空间信息的表达更符合人类空间认知的一般规律,本文从对传统的GIS地理空间认知模型的分析与对比入手,结合全空间信息系统的特点与空间认知的相关研究成果,构建了全空间信息系统的空间认知模型,并得出了全空间信息系统空间认知模型的两个基本单位——多粒度时空实体与多粒度时空对象,为全空间信息系统建模与表达奠定了基础。
Aim To explore the patterns of pan-spatial cognition and match the presentation of pan-spatial information with the features of their spatial cognition.Beginning with analysis and comparison of traditional models of spatial cognition,and in combination with the characteristics of pan-spatial information system and the relative results researched by spatial cognitive,the spatial cognition model of pan-spatial information system has been built,and found that the multi-granularity spatio-temporal entities and the multi-granularity spatio-temporal objects are the two basic units of pan-spatial information system′s spatial cognition model.Both of that has lay a foundation for the modeling and presentation of pan-spatial information system.
