Geographic analysis-oriented Virtual Geographic Environment: Framework, structure and functions

摘要:针对目前虚拟地理环境侧重表达、忽略地理分析的现状,从现代地理学研究与发展前沿需求出发,探讨了可支撑地理分析与模拟的虚拟地理环境的框架、结构与功能。围绕虚拟地理环境的构建理论和实现技术,分析了面向地理分析的虚拟地理环境的建设目标,构建了虚拟地理环境整体框架;将虚拟地理环境分为数据环境、建模环境、表达环境与协同环境四个子环境,深入解析了各子环境的功能、关键技术与研究思路,为虚拟地理环境进一步发展及虚拟地理环境平台研制与开发提供参考。

Abstract: Previous research on the Virtual Geographic Environment (VGE) has focused mainly on representation rather than geographic analysis. However, geographic analysis plays a significant role in modern geography. To address this issue, this paper systematically examines theories and implementing VGE techniques that support geographical analysis and simulation. Based on its framework, VGE can be divided into four subtypes. These are the data environment, modeling environment, expression environment, and collaborative environment. The functions and key techniques of each are examined, and some case studies are discussed. This study provides direction for necessary new developments of advanced VGE platforms.
