Expression of spatio-temporal topological relationship based on the base state with amendments model
Cao Yangyan · Journal of Zhejiang University(Science Edition) · 2014
The traditional model of the base state with amendments can only record explicitly the changes of parentchild relationships and the types of parcels,but it can't solve the problem of associated query between two different time snapshots.The theory of geographical events was introduced and the events increment files were used to solve the association problem of temporal topology and spatial topology between different versions of the database.Combining the model of temporal topology with that of spatial topology,81 kinds of spatio-temporal data topology relations were comprehensively displayed.In terms of the verification of the incremental updating process of cadastral database,the above-mentioned model can fully show and store the spatio-temporal topology relationships,and implement the spatio-temporal query by the improved STSQL language.It can express the temporal and spatial topological relations intuitively.This model can be applied in spatio-temporal data management.
