A 3D GIS's Spatial Data Model Based on Cell Complex
3D GIS non manifold cell complex spatial data model spatial data structure
2015/12/3
Based on cell complex theory, after analyzing the corresponding relationship among cell, cell complex and 3D spatial solid, a formal definition for 3D spatial solid is presented. Through analyzing the...
STUDY ON SPATIO-TEMPORAL DATA MODEL AND VISUALIZATION TECHNIQUE
Spatio-temporal data model Temporal database Spatio-temporal database Visualization

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 ...
RESEARCH ON UNIFIED SPATIOTEMPORAL DATA MODEL
Spatiotemporal Data model Spatiotemporal Changes Object-Relational Database

Spatiotemporal data model, which is the basis of spatiotemporal data management, deals with the representation and manipulation of spatiotemporal data. So far many spatiotemporal data models have been...
FEATURE-BASED SPATIO-TEMPORAL DATA MODEL AND ITS APPLICATION IN LANDUSE MONITORING
Spatio-temporal data model feature state of the changing feature-based spatio-temporal data model (SCFSTDM) temporal landuse information system
2015/8/10
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...
CONCEPTUAL DESIGN OF AN ACTIVITY-BASED SPATIO-TEMPORAL DATA MODEL FOR EPIDEMICS TRANSMISSION ANALYSIS
Epidemics Transmission Activity-Based Modelling Spatio-Temporal Data Model
2015/8/10
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 ...
AN OBJECT-ORIENTED SPATIO-TEMPORAL DATA MODEL
Spatio-Temporal Data Model Oriented Object Space-Time Composite Spatio-Temporal Element Topological Analysis TGIS
2015/8/10
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...
