【摘要】 结合自然资源业务需求,分析了国土资源"一张图"数据平台传统技术架构的不足。在介绍分布式计算发展现状与趋势的基础上,提出了基于云计算架构的自然资源分布式GIS服务平台建设目标。在设计平台总体架构的基础上,重点阐述了基于Hbase的海量空间数据存储、检索和查询方法,阐述了基于Spark的分布式GIS计算方案以及基于MPP架构的海量数据渲染模型设计等关键问题。本研究与相应的开发试验为自然资源分布式GIS服务平台的建设落地提供了可借鉴的技术思路。更多还原

【Abstract】 According to the business needs of natural resources, this paper analyses the shortcomings of the traditional technical framework of the "one map" data platform for land resources. On the basis of introducing the development status and trend of distributed computing, it puts forward the construction goal of natural resources distributed GIS service platform based on cloud computing architecture. On the basis of the overall architecture of the platform, this paper focuses on the storage, retrieval and query methods of massive spatial data based on HBase, and expounds the calculation scheme of Distributed GIS based on spark, and the design of massive data rendering model based on MPP architecture. This research and development experiment provides technical ideas for the construction and implementation of natural resources distributed GIS service platform.更多还原
