4D Geo-referenced Database Approach for GIS

چکیده
Since developments of computerised information systems practically used in the market, many things has been swiftly and progressively changed in surveying profession; because the volubility of the positioning/spatial information has been well understood by the other professions who deal with the information systems. In fact, at the beginning, information systems have been developed without any spatial information of the other information. However in a short time system developers have been realised that information integrated with its geospatial information provide precise results for strategy developments and decision making. That was also the demands of the systems’ users. This is truth that in that case it is possible to support query results with graphical visualisation geographically. Therefore information systems have been began integrating with maps and hence applications of Geographic Information Systems have been started.

An Updating System for the Gridded Population Database of China Based on Remote Sensing, GIS and Spatial Database Technologies
The spatial distribution of population is closely related to land use and land cover (LULC) patterns on both regional and global scales. Population can be redistributed onto geo-referenced square grids according to this relation. In the past decades, various approaches to monitoring LULC using remote sensing and Geographic Information Systems (GIS) have been developed, which makes it possible f...

متن کاملRCC11: A Finer Topological Representation for the Alignment of Regions in Sketch Maps
During the last two decades, dozens of qualitative representations have been proposed. These representations are motivated by a wide variety of applications of spatial data processing such as Geographical Information System (GIS), robotic navigation, and high level vision. For topological reasoning, the Region Connected Calculus (RCC) is perhaps the best-known formalism. The two algebras, RCC5 ...
متن کاملFusion of Geo-Referenced Data for Visual Simulation in Location-based Mobile Computing
Mobility is an emerging concept in the GIS (Geographic Information Systems) domain and according to some specialists it will introduce a revolution on the way GIS users interact with their data. With this paper, we propose a system architecture for a global, fully mobile and location based GIS system, creating an abstraction to support generic multi-level geo-referenced data, from satellite ima...
