摘　　要：本文针对海量DEM串行化生成处理效率低、数据准备过程繁杂等技术问题，充分利用云计算技术的虚拟存储、跨平台应用、计算和存储资源高效调度、软件架构和服务可重组共享等特点，提出了基于云计算的DEM生成算法模型，设计了基于云计算的DEM生成处理模型，并对软件进行改化。通过实验分析，基于云计算的DEM生成技术处理效率提高显著。In vien of the problems that low efficiency of massive DEM generating and complex data preparing, the paper proposes an algorithm model of DEM generating and designs a processing model based on the characteristics of cloud operating, such as virtual storage, cross platform, efficient scheduling computing and storage resources, reassemble and share of software ar- chitecture and services. Besides, the paper modifies the related software. The experiments results show that the new technology based on the cloud operating can improve the processing efficiency of DEM generating.
