A GPS Trajectory Map-Matching Mechanism with DTG Big Data on the HBase System
Wonhee Cho, Eunmi Choi · 2015
Since smartphones equipped with GPS have been produced, the need to conduct an analysis by matching the mass of GPS trajectory data on a digital map has increased. However, the study of the existing map-matching algorithm technique is mainly for navigation. In order to analyze large amounts of GPS trajectories on a server, issues of the speed and performance of the system exist. The purpose of this study is to utilize a map-matching system using HBase, which is a distributed NoSQL DB in a Hadoop ecosystem. We defined the table specification of HBase for mounting the digital map and proposed and implemented the method for analysis with a map-matching algorithm. In this paper, we present the map-matching methodology using the NoSQL DB of Hadoop ecosystem for analyzing GPS trajectory.
