基于面向对象的数字城市地理空间框架数据组织方法

摘要

在探讨基于面向对象空间数据模型( OOSDM)的基础上,研究了数字城市地理空间框架的体系结构、基础数据组织方法和存储管理模式,以及采用OOSDM进行地理空间数据组织的过程.重点研究了数字城市地理空间框架中基础地理空间数据面向对象的数据分类、组织、一体化存储管理与显示,为数字城市地理空间框架建设提供了基于面向对象的数据组织方法和思路.%Geospatial data infrastructure is the basis in digital city application development. Based on the object-oriented spatial data model ( OOSDM ) , the architecture system of digital city geospatial framework, data organization method and related management style are discussed. The development process of geospatial data is introduced by OOSDM. With the basic geospatial data in geospatial framework as an example, the geographic information is classified as various object entities, and the methods for data organization, storage, management and map visualization are explored. The OOSDM-based approach to data management method provides a new way for the digital city geospatial framework development.
