摘要
分析三维道路景观系统应具有的关键技术,为以道路为载体的技术项目提供指导,将基于云GIS的三维道路景观系统分为道路景观数据云特征、三维构建与云模型和应用场景三部分。三维数据的云特征是采用云GIS平台的必要条件,在三维构建与云模型部分中,指出三维构建算法与云模型结合的关键技术,应用场景部分阐述三维道路景观的实际应用。三者共同为三维道路景观系统的合理组建提供必要指导。
This paper analyzes the key technology of three-dimensional road landscape system,divides cloud GIS-based three-dimensional road landscape system into road landscape data cloud characteristics,three-dimensional construction and cloud model and application scenario.Cloud characteristics of three-dimensional data is necessary to adopt cloud GIS platform.The key technologies of combination of three-dimensional construction and cloud model are pointed out,and the practical application of three-dimensional road landscape are expounded.The three provide vital support for reasonable construction of three-dimensional road landscape system.
