基于HBase的瓦片索引和读取方法设计
DESIGN OF TILE INDEX AND QUERY METHOD DESIGN BASED ON HBASE
摘要
Abstract
Geographic information tile data is so large that traditional relational databases are not sufficient to support the capacity,speed and type of tile data.In this case,HBase is selected to store tile data.On the basis of quadtree encoding as an index for data storage,a multilevel tile data index design method is proposed.The algorithm made the tile data adjacent to each other in the map as adjacent as possible in physical storage to achieve the purpose of maintaining the spatial continuity of tile data in physical storage.A neighborhood pre-reading method was proposed,which worked with index design to pre-read neighborhood tiles into the cache based on batch reading.Experiments show that this method has a higher hit ratio and faster response than traditional data index design when users continuously read the associated map data.关键词
