【摘要】：隨著GIS在各行業(yè)的廣泛應用，加上人們對空間數(shù)據(jù)的精度要求也不斷在增加，，于是GIS中需要管理的空間數(shù)據(jù)越來越多，數(shù)據(jù)量也越來越大近年來，分布式存儲和并行計算的不斷發(fā)展為海量空間數(shù)據(jù)的存儲和處理提供了一個新的方向然而，目前在分布式環(huán)境下對于海量空間數(shù)據(jù)的存儲和處理大部分是基于傳統(tǒng)關系數(shù)據(jù)庫，對于二三維的海量空間數(shù)據(jù)存儲效果不理想，其獨有的關系模型束縛對海量空間數(shù)據(jù)的快速訪問和處理能力因此，分布式環(huán)境下如何利用非關系數(shù)據(jù)庫和并行處理技術實現(xiàn)海量空間數(shù)據(jù)的高效存儲和快速處理具有重要的研究意義 首先比較分析目前幾類典型非關系數(shù)據(jù)庫的特點，提出了非關系數(shù)據(jù)庫MongoDB的對于海量數(shù)據(jù)存儲優(yōu)勢在總結空間數(shù)據(jù)的特點基礎上，設計了海量空間數(shù)據(jù)在MongoDB中的存儲方式為了驗證MongoDB對于海量數(shù)據(jù)存儲的可行性，與關系型數(shù)據(jù)庫SQLSERVER進行了數(shù)據(jù)插入查詢實驗比較接著根據(jù)上述的存儲方式，結合了并行處理框架Hadoop的MapReduce實現(xiàn)海量空間數(shù)據(jù)的并行處理最后設計實現(xiàn)了基于Hadoop+MongoDB的HMGIS數(shù)據(jù)庫管理器，并在多臺Linux服務器上搭建了HMGIS的分布式環(huán)境，通過利用HMGIS進行海量空間數(shù)據(jù)導入和多種空間查詢等并行處理實驗證明HMGIS的可行性和高效性 主要取得的研究成果： τ1υ利用MongoDB來對非結構化的海量空間數(shù)據(jù)存儲是可行的； τ2υ利用Hadoop的MapReduce結合MongoDB數(shù)據(jù)庫實現(xiàn)的HMGIS數(shù)據(jù)庫管理器在海量空間數(shù)據(jù)的多種查詢方面比傳統(tǒng)關系數(shù)據(jù)庫具有更高的訪問和查詢效率； τ3υHMGIS設計實現(xiàn)可以進一步為海量空間數(shù)據(jù)的分析和復雜的地理計算提供軟件支持
[Abstract]:With the wide application of GIS in various industries and the increasing demand for spatial data accuracy, more and more spatial data need to be managed in GIS, and the amount of data is becoming larger and larger in recent years. The continuous development of distributed storage and parallel computing provides a new direction for the storage and processing of massive space data. At present, most of the storage and processing of massive spatial data in distributed environment is based on the traditional relational database, which is not ideal for two or three dimensional mass spatial data storage, and its unique relational model restraints the rapid access and processing power of massive spatial data, and how to use non relation under the distributed environment. Database and parallel processing technology are of great significance for efficient storage and rapid processing of massive spatial data.
First, the characteristics of several typical non relational databases are compared and analyzed. On the basis of the characteristics of massive data storage in the non relational database MongoDB, the storage mode of massive spatial data in MongoDB is designed to verify the feasibility of MongoDB for mass data storage and the number of relational types. According to the storage mode of data insertion and query according to library SQLSERVER, the parallel processing of the parallel processing framework Hadoop MapReduce is combined to implement the parallel processing of massive spatial data. The HMGIS database manager based on Hadoop+MongoDB is designed and implemented, and a distributed loop of HMGIS is built on a number of Linux servers. The feasibility and efficiency of HMGIS are proved by parallel processing experiments such as massive spatial data import and multiple spatial queries using HMGIS.
The main achievements of the research are:
It is feasible for MongoDB 1 to store unstructured massive spatial data.
The HMGIS database manager, implemented by Hadoop MapReduce and MongoDB database, has higher access and query efficiency than traditional relational database in many queries of massive spatial data.
The design and implementation of HMGIS 3 can further provide software support for massive spatial data analysis and complex geographic computation.
