Big-Data framework-based visualization solution for performance analysis of positioning systems in railway environments

Abstract

The on-board positioning system provides not only the location estimation but also additional information about the certainty or quality of the provided estimation. Additionally, when developing the positioning system itself and evaluating the performance of the system, it is useful to thoroughly analyze the input parameter values used by the positioning system for each of the location estimates. A visualization platform based on Big-Data frameworks was highly demanded in this context and several alternatives were analyzed. This paper describes the approaches that have been tested and implemented, describes the difficulties and advantages of the alternatives and provides detailed steps for adapting the open-source Big-Data framework-based solutions to other application areas.
