In this paper, we present the H-Change methodology we have specifically conceived for evolving independent ontologies in open networked systems. Furthermore, we describe the change detection techniques based on semantic matchmaking for determining the most appropriate location where to frame new incoming knowledge within an existing ontology. Change assimilation techniques for evolving ontology...

In this paper a spatial database for telecommunications geographic information system and its applications are presented. This spatial database has been created using methodology established at the Computer Graphic and GIS Lab at the Faculty of Electronic Engineering in Nis. This database is essential part of telecommunications GIS GeoTT which is intended to input, store, retrieve and show data...

This paper introduces a new intelligent method to generate vector maps from printed maps to provide a basis for GPS navigation. This new approach has been applied in our GIS-DMG (Digital Map Generation) software, which has four key steps: Map Layers Extraction, Road Network Digitalization, Map Geo-locating and Map Automatic Geo-adjusting, different from typical procedures. These four steps play...

Time-critical logistics (TCL) refer to time-sensitive procurement, processing and distribution activities. A confounding factor is the transportation networks that contain these logistic systems. This paper reports on a GIS-based decision support system for dynamic congestion modeling and shortest path routing in TCL. The system predicts network flow at detailed temporal resolutions and solves ...

The Internet technology has already changed the Information Society in profound ways, and will continue to do so. Nowadays many people foresee that there is a similar trajectory for the next generation of Internet Grid Technology. As an emerging computational and networking infrastructure, Grid Computing is designed to provide pervasive, uniform and reliable access to data, computational and hu...

The truthfulness and understandability of information is dependent upon the way it is presented. It is admitted now that almost 85% of the data in human brain is related to geography and we continuously keep upgrading urban information in our brain consciously or unconsciously. This information, if updated frequently, affects most of the decisions made in our life. Maps are considered an easy a...

With the progress of mobile GIS technology there is a great potential for adopting wireless communications and Internet mapping services for regional environmental management programs and natural habitat conservation. This paper provides an overview of a NASA-funded research project that focuses on the development of mobile GIS tools and wireless Internet Map Server (IMS) services to facilitate...
