摘要
为提升高精度卫星(航空)影像数据、实景三维数据、激光雷达点云等海量地理空间数据的安全保障、高效流转和生产效率等综合治理能力,本文提出引入软件定义方法构建地理空间大数据IaaS云平台,实现计算资源、存储资源、网络资源、安全资源等基础设施资源的统一管理、按需分配和灵活调度。该方法可以将新旧资源统一管理,提升资源利用率,达到保护投资的目的;还可以通过“不落地流转方式”消除传统硬拷贝存在的数据泄密隐患,实现业务系统的快速部署,确保成果数据的版本一致性,从而提高数据生产效率。测试实例表明,在资源配置相仿的情况下,与传统计算机集群相比,基于软件定义的地理空间大数据IaaS云平台,分析和处理倾斜摄影数据的效率提升了近1/3。
In order to improve the security,efficient circulation and production efficiency of massive geospatial data such as high-accuracy satellite(aviation)image data,real scene 3D data and LiDAR point cloud.It is proposed to introduce the software-defined method to build the geospatial big data IaaS cloud management platform to realize the unified management,on-demand allocation and flexible scheduling of infrastructure resources such as computing resources,storage resources,network resources and security resources.This method can unify the management of old and new resources,improve resource utilization,and achieve the purpose of protecting investment.It can also prevent the hidden danger of data leakage existing in traditional hard copy through"non-landing circulation",realize the rapid deployment of business system,ensure the version consistency of achievement data,and improve data production efficiency.The test example shows that under the condition of similar resource allocation,compared with the traditional computer cluster,the efficiency of analyzing and processing tilt photography data based on the software-defined geospatial big data IaaS cloud management platform has been improved by nearly one third.
