Evolvement and Progress of Spatio-temporal Index
Chong Zhang · 2010
With the development of mobile computing and wireless communication technology in recent years,the spatio-temporal databases have been widely applied in traffic control and global position.A great deal of spatio-temporal indices were proposed for supporting spatio-temporal query and managing massive spatio-temporal objects efficiently.Firstly,summarized the spatio-temporal indices and drew,the evolvement graph,introduced the spatio-temporal query types,then divided the spatio-temporal indices into four types including past,current,future and complete tense accor-ding to time,and two types including moving point and moving area according to space,based on the categories expatiated the spatio-temporal indices,finally discussed the directions for further work.
