Compression Of Gps Trajectory Data : Benchmarking Framework And New Approach, Jonathan Muckell
Compression Of Gps Trajectory Data : Benchmarking Framework And New Approach, Jonathan Muckell
Legacy Theses & Dissertations (2009 - 2024)
GPS-equipped mobile devices such as smart phones and in-car navigation units are collecting enormous amounts of spatial and temporal information that traces a moving object's path. The exponential increase in the amount of such trajectory data has caused three major problems. First, transmission of large amounts of data is expensive and time-consuming. Second, queries on large amounts of trajectory data require computationally expensive operations to extract useful patterns and information. Third, GPS trajectories often contain large amounts of redundant data that waste storage and cause increased disk I/O time. These issues can be addressed by algorithms that reduce the size …
