Analysis and Design of the Geospatial Information and Service Integration System for Digital City
数字城市空间信息与服务集成交换平台系统分析与设计

Based on the analysis of the geospatial information sharing from multiple views of syntax, semantics and pragrnatics, possible approaches to implement it are discussed. By integrating and improving existing technique, a consolidated technical framework is proposed. As an implementation of the technical framework, the basic architecture of a software platform, called CyberGIS XP, is illustrated. Corresponding prototype of CyberGIS XP, as a part of the Digital Baijing Pilot, is described in the end.
