Research on feature based spatial data similarity query
Chunhui Zhou · Computer Engineering and Applications Journal · 2007
Aiming at the general demand of spatial data similarity query and the state of its application at present,the concept of Feature Based Spatial Data Similarity Query has been proposed in this paper,and then the formal definition has been given,at the same time the features of FBSDSQ have been proposed and analyzed.The uniform framework and the key technologies of FBSDSQ have been given.In particular,with an example of high dimensional index structure in metric spaces,called VP tree,distance based high dimensional indexing in metric spaces has been discussed which provides technical support for spatial data similarity query.
