Therefore, diverse visualization methods that present the value of massive trajectory information are currently a hot research topic. ... This paper summarizes the research status of trajectory data-visualization techniques in recent years and extracts common contemporary trajectory data-visualization methods to comprehensively cognize and ... However, this approach usually fails to deal with massive points and requires much computational time  . ...doi:10.3390/ijgi8020063 fatcat:fjd5jjfrhncfpowutovxxiyhpe
Visual querying is essential for interactively exploring massive trajectory data. However, the data uncertainty imposes profound challenges to fulfill advanced analytics requirements. ... On the other hand, domain experts and general users prefer a natural way, such as using a natural language sentence, to access and analyze massive movement data. ... ., hotel.), which motivates us to develop new approach that integrates natural language based query with uncertain trajectory data. ...doi:10.1109/tvcg.2019.2934671 pmid:31443013 fatcat:pa7womdqdrasnl6awvhoynuuhi
