Temporal Geographic Information System (TGIS), which aims to collect, manage and analyze dynamic geographic phenomena, is a hot scientific research field. The all-important task of developing a TGIS i...
Spatio-temporal database is a application base of Temporal GIS, meanwhile, its basic theory is spatio-temporal data model. Traditional GIS, often was be called Static GIS, generally not keep the hist...
3D data model is the better model at present, but it can’t describe the temporal and changes, can not describe the dynamic characteristic. So, we need introduce time to the model, integrate time with ...
Traditional data model takes the geometric object as the modeling target and results directly in decomposing geographic phenomena into a series of objects. Furthermore, the temporal data and spatial d...
Recently GIS have been used in the surveillance and monitoring of diseases and control of epidemics. Most of those mapping systems use aggregated datasets. This aggregated datasets are not sufficient ...
The paper proposes an object-oriented spatio-temporal data model based on space-time composite by taking advantage of high topological representation ability of the space-time composite data model and...
Presently, planning and assessment in maintenance, renewal and decision-making for watershed hydrology, water resource management and water quality assessment are evolving toward complex, spatially ...
