一种基于TMS的瓦片金字塔切分方法

摘要

为了有效提高大数据量下的切片效率, 从瓦片地图服务 ( Tile Map Service, TMS) 元文件、 瓦片划分规则和瓦片命名规则等方面对TMS技术进行了研究, 对切片算法进行了设计实现, 并结合多线程机制进行了优化改进, 从而提出一种基于TMS的瓦片金字塔切分方法. 试验结果表明, 该方法能提高瓦片的切片效率.%For raising slice efficiency effectively under of big data quantity,research is performed on TMS technology,its metafile, the rule of tile slicing,tile naming and so on.A realization of TMS slice algorithm is designed.And a kind of method is put forward that tile pyramid slicing based on TMS,which improves slice algorithm combined with multithreading.Experiment results show that this meth-od can raise the slice efficiency of tile.
