Spatio-temporal indexing methods for moving objects for highly interactive environment

Deals with spatio-temporal indexing methods for moving objects. Spatio-temporal indexing gives a basis for a data management structure for the efficient searching of large-scale spatio-temporal data. In this paper, two types of indexing methods are proposed for managing spatio-temporal data for moving objects. Both methods are evaluated by computer simulation and the merits and demerits of both methods are discussed. These methods can be used to realize a highly interactive environment including moving objects
