This paper presents the software life-cycle for the development of a knowledge-based GIS. The life-cycle framework used is called MBIUI and provides the experimental studies that are required for designing, implementing and testing a decision making theory in a graphical user interface. The decision making theory has been adapted in the user interface for is used for the evaluation of different...

The objective of this work is to develop a dynamic geographical information system (DGIS) applicable for the simulation of spatio-temporal phenomena. DGIS is designed and implemented as a dynamic raster GIS in a fully integrated systems strategy using theory of modelling and simulation, discrete event systems speciŽ cations, and knowledge-based simulation methodologies. The approach accommodate...

The paper proposes to use CR-prolog to add planning capabilities to a Geographical Information System. Cr-rules can restore the consistency of a program giving the diagnosis of possible causes of failure in a plan. In this paper we give an additional use for cr-rules: we propose to use cr-rules to obtain an alternative plan in case of the ideal plan fails. They not only restore consistency and ...

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...

The idea of the creative individualist spawning innovations as a solitude effort is no longer realistic. Huge innovation projects, relying on project teams, have to be permanently conducted by organizations to assure their competitiveness. These projects often take place in distributed teams, making use of groupware to bridge temporal and geographical distances. Research in social psychology on...

the Gdansk City Hall Crisis Management Department (CMD). The system works as an integrated solution for both visualization of hazard scenarios and a team-enabled environment for information analysis and sharing among geographically distributed decision makers. The paper focuses on the sample applications with reference to the analysis, visualization, and mapping in a geographical context of sev...

This paper presents a data model and some considerations on the path operator to manage networks with a Geographical Information System. The data model is based on the merge of the graph theory concepts and the object-oriented paradigm. The introduction of the Master_nodes (resp. Master_edges) allows to define a node (resp. an edge) as an abstraction of a sub-network. A network can be defined u...

Nowadays, the construction of a Geographical Information System on a commercial package takes up a great deal of time and resources. However, the distribution of such an application can be more expensive than the construction because of the need to distribute the commercial package with the application. Usually, commercial packages cover this lack by providing reduced versions from their powerf...
