With the rapid development of wireless sensor and information technology, there is a trend of transition from "digital monitoring" to "intelligence monitoring" advancing process. The traditional model...
We are witnessing a dramatic increase of large engineering data resource availability and accessibility.
This paper presents the generation of the 3D national building geo-data model of Turkey, which is compatible with the international OGC CityGML Encoding Standard. We prepare an ADE named CityGML-TRKBI...
This paper describes phases of the development and results of an experimental structure of numerical cartography, at medium and large scale, to be used in GIS and to be proposed as a national standard...
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...
After 9/11 there has been special interests in 3D models to represent internal structures of micro-scale environment (built-in urban areas), in order to understand and analyze human movements under su...
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...
The data model for navigable electronic map need to created based on an syncretic model of multi-layer roadway network, as the evolution of the navigation information technology, the rapid extension o...
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 ...
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...
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...
Panoramic images portray a surround view of the real world in one image. This kind of presentation however does, alike regular pictures, not give any real depth information. Depth related relationship...
