Geospatial ontology plays a key role in Geospatial Semantic Retrieval (GSR), which provides support for query expansion and disambiguation, relevance ranking and web page annotation. However, existing ontologies are deficient in representing and reasoning fuzzy geospatial information, an important type of information that distributes widely in user’s queries and web pages. This paper proposes a...

Geospatial technologies have evolved to offer users the functionality of data access and to model development to generate information. Nowadays Spatial Data Infrastructures represent the SOA paradigm in geospatial terms offering a set of interoperable distributed components to access, visualize and process data forming the Geospatial Web. Fostered by the European directive INSPIRE many public a...

MICHALAK, J. & LEÊNIAK, P.M. 2003. Features and coverages in hydrogeological information. Acta Geologica Polonica, 53 (3), 247-255. Warszawa. In recording hydrogeological information in computer systems (databases, GIS), it became necessary to manipulate them in a consistent and efficient way. The correct functioning of these systems depends principally on the applied data models, which should ...

The adoption of multimedia (MM) in the development of new learning and teaching materials is experiencing a rapid growth. MM and other computer-aided tools have been tried in Geographic Information Systems (GIS) education since its early days. However, until detailed evaluations are conducted, many MM curriculum transformations may simply be seen as experiments in technological innovation rathe...

The purpose of this paper is to provide an introduction to geographic information systems (GIS) and a research framework for information systems researchers. The paper summarizes the main GIS features, functions, and capabilities, including a research framework for GIS. In addition, several opportunities for research are suggested including those related to GIS management, organizational impact...

That's it, a book to wait for in this month. Even you have wanted for long time for releasing this book information fusion and geographic information systems towards the digital ocean; you may not be able to get in some stress. Should you go around and seek fro the book until you really get it? Are you sure? Are you that free? This condition will force you to always end up to get a book. But no...

This paper introduces a process for developing Web GIS (Geographic Information Systems) applications. This process integrates the NDT (Navigational Development Techniques) approach with some of the Organizational Semiotic models. The use of the proposed development process is illustrated for a real application: the construction of the WebMaps system. WebMaps is a Web GIS system whose main goal ...

Spatiotemporal database management systems can become an enabling technology for important applications such as Geographic Information Systems (GIS), environmental information systems, and multimedia. In this paper we address research issues in spatiotemporal databases, by providing an analysis of the challenges set, the problems encountered, as well as the proposed solutions and the envisioned...

Geographic Information Systems (GIS) represent an application of information technology (IT) in business that has yet to reach full maturity. Like other forms of information system (IS), the development of GIS in commercial organizations has been greatly influenced by developments in IT and in the subsequent availability of software to exploit these developments. However the corporate use of GI...

This paper shows a number of sceneries where information (specifically, geographical-related information) is lost because there is no method for storing or sharing it. This research has been done with the aim to solve those scenery problems in a general way, by means of a geographical information system that can store geographical-related information and publish it in order to avoid loss of inf...
