摘要
提出一种基于MBTiles的地图瓦片存储技术,规避了SQLite不支持并发写数据的特点,缩短了地图瓦片数据的存储时间,提高了数据的读取速度,且易于备份和迁移,使基于Web的GIS地图服务能更好地满足大规模用户的需求。
In this paper,we presented a map tile storage method based on MBTiles.This method can avoid the characteristic that SQLite does not support concurrent data writing,shorten the storage time of map tile data,improve the data reading speed,and make it more convenient to backup and migrate.The method can help the GIS map service based on Web better meet the needs of large-scale users.
