Abstract. User Oriented Geographical Information Systems, a recent adaptation of classical GIS concepts to everyday usage, are becoming more and more present in the web landscape. Recent developments show the need of adding higher semantic levels to the existing frameworks, to improve their usage, as well as to ease scalability. We point out limits of actual examples, related to handling hetero...

Combined research in the fields of Geographical Information Systems (GIS), transportation modelling and traffic systems has in fact finally reached the point where paths should overlap and continue in better unison between these different domains. This paper introduces methodological and experimental results of several integrated projects that include traffic monitoring systems, GIS and several...

The geographical information system (GIS) revolution started in the mid 1980s and has since snread to all countries of the world. A GIS is a comput&software package that is concerned with the capture, storage, manipulation, query, display and analysis of any and all types of geographical information, (BLJRROUGH, 1986; CHORLEY, 1987; LAURINI & THOMPSON, 1992; ESRI, 1993). There are now many diff...

Ontology, which derives from philosophy, is a discipline of Philosophy that deals with existence. In recent years, it has been widely used in artificial intelligence and computer science, mainly representing, sharing and reusing knowledge. So it's significant to introduce ontology into Geographic Information Science for the implementation of the geographical information representation, sharing ...

Geographical information is achieving an increasing importance in the World Wide Web. Recently, the web saw a growth in the use of map-based services; however, these services are usually used as visual yellow pages rather than search engines. The action of finding a web page relevant to a specific topic and a specific area is still mostly dependent on classical keyword based methods. In this pa...

A review of some Geographical Information Systems dedicated to humanitarian demining is presented together with PARADIS, a Prototype for Assisting Rational Activities in Demining using Images from Satellites, designed for the Mine Clearance Service of the Belgian Army.

We discuss the development and application of Web Service-based Geographical Information System Grids. Following the WS-I+ approach of building Grids on Web Service standards, we have developed Data Grid components for archival and real-time data, map generating services that can be used to build user interfaces, information services for storing both stateless and stateful metadata, and service...

Non-relational databases are the common means of data storage in the Cloud, and optimizing the data access is of paramount importance into determining the overall Cloud system performance. In this paper, we present GAIA, a novel model for retrieving and managing correlated geo-localized data in the cloud environment. We survey and compare the existing models used mostly in Geographical Informat...

The current expansion of the Internet makes it one of the most popular places to publish and search for almost any kind of information. In particular, touristic information—not only about tours or information about resources, places, museums, or monuments, but also cultural tourism—has gained much attention in the last years. We propose the use of geographical information systems (GIS) technolo...
