基于Lucene的图斑快速检索技术

Fast Searching Technique of Map Spot Based on Lucene

嵌入式GIS中矢量电子地图数据量越来越大,有时又需要快速检索出某些特定的空间对象,针对这一需求,本文通过比较Lucene全文检索工具和SQLite数据库检索各自的优缺点,提出了利用全文检索框架Lucene实现高效的地图属性检索功能,并经过测试证明了该方法的可行性与高效性。

In view of the need that vector electronic map data has been becoming more and more largeand sometimes requires rapid retrieving a certain space object in embedded GIS, this paper proposes the use of full - text retrieval framework of Lucene to realize efficient map spot retrieval by comparing the advantages and disadvantages between Lucene and SQLite. The test result shows its feasibility and efficiency.
