摘要: 针对应用地理标记语言(Geography Markup Language,GML)表示的海量空间数据查询问题,提出一种基于MapReduce的GML并行查询方法。通过提取GML空间特征集合,实现GML文档查询到GML空间特征集合查询的查询转化,并利用MapReduce实现空间特征并行查询。

关键词: 地理标记语言,GML查询,MapReduce,并行查询

Abstract: A novel GML distributed query method based on MapReduce model was proposed to deal with queries with large amount of GML data.Some pretreatments are taken with the original GML files to generate GML feature set before the queries,and the queries are converted from GML files to GML Feature Set.The queries can execute in a parallel way and be more efficient.

Key words: GML,GML query,MapReduce,Parallel query
