THE METHOD INNOVATION AND GEOGRAPHICAL APPLICATIONS OF MOBILE POSITIONING DATA:A REVIEW OF RESEARCHES FROM REIN AHAS

本文对爱沙尼亚塔尔图大学人文地理学教授Rein Ahas基于手机定位数据的方法创新与地理研究做了相对全面的梳理与综述。随着信息与通信技术的快速发展以及手机的大规模普及,手机定位数据可以突破有限的时空框架,实现海量、客观、实时、准确和电子编码的数据收集,从而便于研究者发现人的时空间行为模式和规律。Ahas以社会定位法为主线,以手机定位数据为主要数据源,以地理可视化为分析手段,不断地通过时空间行为和活动空间研究参与到旅游、通勤、交通、社会隔离和智慧城市等多样化的领域中。他的研究方法及经典案例有助于国内学者扩宽视野,更加深入理解这一新型数据源的使用特点和应用潜力,并进一步对其进行理论与方法上的挖掘与探讨。

This paper makes a relatively comprehensive review of the mobile positioning data-based method innovation and geographical applications of Rein Ahas,a professor of human geography at Tartu University in Estonia.With the rapid development of information and communication technology as well as the largescale usage of mobile phones,mobile positioning data has shown obvious advantages over the conventional data sources like travel diaries,questionnaires,accommodation statistics and census.It has been proved that mobile positioning data can be collected for a much bigger sample of people,a longer period of time and a larger study area,so as to break through the limited spatiotemporal framework.In addition,mobile positioning data can be massive,objective,real-time,accurate and electronically coded,which helps facilitate researchers and urban planners to discover the patterns and laws of human space-time behavior in the daily life.Rein Ahas is one of the first scholars in the world to use mobile positioning data to carry out researches on human space-time behavior.He’s also the leader in this field.His researches are experimental and pioneering,showing the valuable exploration made by the international academy in the early stage of understanding and using mobile positioning data.Rein Ahas formally put forward the Social Positioning Method(SPM)in2005,which provides a new research paradigm for human space-time behavior.Using SPM as the main method,using passive mobile positioning data as the main data source and using geographic visualization as the main analysis technology,Rein Ahas kept participating in the diversified fields of tourism,commuting,transportation,ethnic segregation and smart city.
