基于云计算的三维地理空间信息服务的表达

当前云计算的发展已能支持高性能的地理空间服务,比如在数字城市和电子商务等行业。Apache基金支持下的开源软件框架Hadoop,可以用来构建一个云环境的集群用来存储和处理高性能的地理空间数据。开放地理空间联盟(OGC)的Web三维服务(W3DS)就是这样一个很好的三维的地理空间数据服务标准。在标准的云计算环境下将是一个更好的应用示范。基于此,本文研究了OGC的W3DS服务在云计算环境下的实验结果。实验采用Apache的Hadoop框架作为三维地理空间信息服务实验展示的基础。实验结果对展示高性能的三维地理空间信息提供了有价值的参考。

The Presentation of 3D Geospatial Information Service Based on Cloud Computing

The development of cloud computing has been able to support the high performance of geospatial services, such as in the digital city and electronic commerce and other industries.The open source software framework Hadoop, which is supported by Apache, can be used to build a cloud environment of clusters for storage and processing of high performance geospatial data.The web three-dimensional service (W3DS) of Open geospatial Consortium (OGC) is such a good standards of three-dimensional geospatial data service.Under the standard, the cloud computing environment will be a better application demonstration.Based on this, the paper studies the experimental results of W3DS OGC services in cloud computing environment.The Hadoop Apache framework is used as the basis for the experimental demonstration of 3D geospatial information service.The experimental results provide valuable references for the high performance 3D geospatial information.
