Description
Description: State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, 129 Luoyu Road, Wuhan 430079, P. R. China. Massive spatial data requires considerable computing power for real-time processing. With the help of the development of multicore technology and computer component cost reduction in recent years, high performance clusters become the only economically viable solution for this requirement. Massive spatial data processing demands heavy I/O operations however, and should be characterized as a data-intensive application. Data-intensive application parallelization strategies are imcompatible with currently available procssing frameworks, which are basically designed for traditional compute-intensive applications. In this paper we introduce a Split-and-Merge paradigm for spatial data processing and also propose a robust parallel framework in a cluster environment to support this paradigm. The Split-and-Merge paradigm efficiently exploits data parallelism for massive data processing. The proposed framework is based on the open-source TORQUE project and hosted on a multicore-enabled Linux cluster. One common LiDAR point cloud algorithm, Delaunay triangulation, was implemented on the proposed framework to evaluate its efficiency and scalability. Experimental results demonstrate that the system provides efficient performance speedup.
