基于时空关系的手机定位数据处理方法

A Processing Method of Mobile Phone Location Data-based on Time and Spatial-Relation

应用手机定位技术进行交通信息的采集是当前国内外研究的一个热点。但是效果并不如人意,其中手机定位数据中包含了大量的"噪声"是一个重要原因。以某区域的手机定位数据作为对象,结合CELL_ID定位技术与手机切换的原理,首先根据蜂窝网基站的点数据,创建了与之对应的点、面图层;然后采用基于GIS时空关系的方法,对手机定位数据中"噪声"数据进行了处理。实验结果证明,该方法可以有效解决上述问题。

Getting traffic information from the mobile phone location data is a hot research topic in recent years.However,the effect does not meet people＇s requirement,one of the most important reason is that there are a lot of ＂noise＂ in the mobile phone location data.First of all,a region＇s mobile phone location data was used to create the Thiessen polygons and point layers based on Cell-ID mobile location technology and mobile phone handover principle,and then the method based on time and spatial-Relation was used to process the noise data reasonably.The experiment result shows that the method is effective and useful.
