摘要
时空数据模型是GIS实现空间数据组织、表达、分析、处理和应用的基础。随着城市信息化建设步伐的加快,地理空间数据模型对地理实体的描述和地理信息的语义表达提出了更高的要求。近年来,众多学者主要从数据及语义模型存在的问题出发,对数据组织与存储进行,但缺乏对地理实体的语义及逻辑结构的研究。以本体的空间认知为基础,将空间存在抽象为地理实体及其逻辑关系,提出了基于本体的城市道路地理空间数据模型的定义、模型结构及构建过程,为空间信息的语义诠释和数据组织一体化提供了新思路。
IS spatial data model is foundation of the spatial data organization ,presentation,analysis,processing and application .With the city accelerated pace of information technology .Geospatial data models has put forward higher re-quirements in semantic of geographic information and describe of geographic entity .In recent years ,many scholars mainly from the perspective of data and semantic models ,Research organization and storage of data ,but the lack of the geograph-ic entity expression of semantic and logical geographic entity structure .In this paper ,based on spatial cognition and ontol-ogy,Abstract entity geographic entities and their logical relationship .Proposed the definition of the structure and the mod-el building process of Construction method of road data model based on ontology .Provides a new idea for the semantic in-terpretation integration and data organization of spatial information .
