关于空间数据与空间数据模型的思考——中国GIS协会理论与方法研讨会(北京,2004)总结与分析

On Spatial Data and Spatial Data Modeling ——Summarization and Analysis of the Theory and Methodology Symposium(Beijing, 2004) of China Association of GIS

空间数据和空间数据模型是GIS理论与方法的核心内容。本文总结中国GIS协会理论与方法研讨会(北京, 2004)的成果,围绕GIS研究与发展的新动向,分析了空间数据组织、集成、质量、不确定性与数据挖掘及3维空间数据建模、空间关系与可视化等方面的理论问题与发展趋势,并思考和讨论了空间认知学与本体论在GIS理论与方法研究中的作用。

Spatial data and spatial modeling are the cores of GIS theory and methodology. This paper gives a summarization and a brief analysis to the academic results from The Theory And Methodology Symposium (Beijing, 2004) of China Association of GIS. Referring to the theoretical study and the developing trend of GIS, the spatial data organization, integration, quality, uncertainty and data mining, as well as the 3D spatial data modeling, spatial relationship, visualization etc., are introduced and analyzed. Besides, the function of spatial cognition and ontology on GIS theory and methodology is discussed.
