Abstract
To efficiently store, query and update trajectories of moving objects in spatio-temporal database, indexing techniques are sticking points. This paper thoroughly analyzed indexing methods for constrained and non-constrained trajectory, andfinally some open researching problems and interesting direction werepresented.
