Query the trajectory based on the precise track: a Bloom filter-based approach
2021
Geoinformatica
Preserved Fulltext
And the Bloom Filter-based query method is hardly affected by grid size, original data size, and length of tracks. ...
Thus, they are not suitable for the time-critical tasks of trajectory big data. In this paper, a query method of trajectory is developed on the Bloom Filter. ...
For the precise query, the query time based on Bloom Filter is much shorter than that based on the R*Tree index. ...
