(English Abstract)
The analysis of trajectory big data for extracting trajectory patterns such as hotspot detection is quite challenging due to the complex data model and the huge volumes of the data. In this paper, we propose a trajectory big data analysis system, called TrajectMesa, which extracts the hotspots from trajectory big data based on Geomesa NoSQL Framework. The hotspot extraction process consists of two steps: (1) detecting stay points where users spend considerable amount of time at and (2) identifying hotspots which are the centroid of several stay points. Thus, our system detects the stay points in the trajectory by grouping some candidate points within certain time range, distance, and minimum point thresholds. Then, TrajectMesa can identify the hotspots from the groups of stay points utilizing DBSCAN based algorithm. We demonstrate the feasibility of TrajectMesa system with the real world GPS trajectory dataset provided by GeoLife project.
