The Identification and visualisation of errors within location based services

  • Adam Jakhara student


This project studied Location based services. The aim of the research was to explore how users of Location Data can identify points which are erroneous and how these data streams and the errors be visualised. The project commenced by conducting a thorough literature review that considered what location based services are, how they work, issues of accuracy and ethical issues. 
The project used a quantitative research design to study the phenomenon. Data from Microsoft Geolife data which is data that was collected by Microsoft Asia between 2007 and 2012 was used. Five journeys were randomly selected   for analysis. Microsoft Excel was used to interrogate the data and produce graphs to visualise the data.
Visualisation of the data highlighted a number of inconsistencies that question the accuracy of location data and the technology that it relies on. The investigation further raised a number of ethical and security issues that centre on the collection of and use of location data.
In response to the findings of the project two key recommendations are made. The first is aimed at increasing the accuracy of location data to give the range of users including individuals, business and community organisations more confidence in the data. The second is aimed at addressing the ethical issues that the project has flagged.
