Research on Association and Search Services of Massive Geospatial Information Based on Cloud Computing

Abstract

Adapt to the global strategy of the state, the paper builds a geospatial information service platform with a global coverage, high resolution, multi-subject, and the national global strategy formulation and implementation, to provide the fusion and strategic decision-making ability of massive dynamic global geospatial information, and provide an independent global geospatial information base for the country's global strategy development, deployment and the national life. To solve the limitations of system performance, stability, expansibility, etc. of the traditional single node architecture of geospatial information service with mass data storage, multi-user concurrent access, through cloud computing of the fusion of the collection computer cluster technology, data storage technology and high-performance network services, the paper achieves association and search services of massive geospatial information, and provides the basis for establishing a geospatial information service platform with the global coverage, high resolution, multi-subject and adapt to the global strategy formulation and implementation. Introduction Adapt to the global strategy of the state, we need a geospatial information service platform with a global coverage, high resolution, multi-subject, and the national global strategy formulation and implementation, to provide the fusion and strategic decision-making ability of massive dynamic global geospatial information, and provide an independent global geospatial information base for the country's global strategy development, deployment and the national life [1,2]. So we begin to research the association and search service of massive geospatial information to establish a geospatial information service platform with the global coverage, high resolution, and multi-subject and adapt to the global strategy formulation and implementation through cloud computing of the fusion of the collection computer cluster technology, data storage technology and high-performance network services [3]. System Architecture and Technology The data scale of global mass spatial data services to meet small and medium scale processing of spatial data ranges from GB or TB-level scale to dozens of TB, hundreds of TB and PB grade scale. Building a global mass spatial data service cluster, eliminating mass spatial data storage and high performance bottleneck of the spatial information service, achieving high-performance spatial information services [4].
