Design Method of GIS Spatio-Temporal Data Model Based on Object
Tian Li-ya · Geography and Geo-Information Science · 2010
GIS spatio-temporal data model is the organism which is used to describe the temporal and the spatial characteristics of spatial entities.It is also the foundation for GIS storage,reproduction,analysis of the dynamic real-world.The study presents the building process of GIS spatio-temporal data model based on object by adopting the object-oriented principle that geo-entities were abstracted as spatial objects whose geometric information,property information and temporal information were encapsulated.Focusing on the exploration of the description method of geo-entities based on object,temporal characteristics of spatial objects and storage method of temporal data,the study provides a new perspective of spatio-temporal data organization and management for the organic integration of spatial-temporal information,sharing management,decision analysis and application.
