Personalization in adaptive and interactive GIS

With continuous increase of available online spatial data, requirements for the adaptation of spatial content to users context becomes increasingly important. Location-based services (LBS) deliver to the user information specific to a given location preferably using mobile devices. Personalizing the information provided to the user to take into account her/his information preferences and current location, the problem of inundating the user with irrelevant information is avoided. The research presented in this paper introduces an approach which implicitly monitors the users activity and generates a user profile reflecting her/his information preferences based on the interactions of the user with the system, and her/his physical location and movements. The system recognizes the user profile and adapts accordingly both to provide suitable information, and to prioritize the functionality appropriate to the users current context.

A contextual approach for the development of GIS: application to maritime navigation

The research presented in this paper introduces the principles of a multi-dimensional contextual approach for adaptive GIS. The framework makes the difference beetween the user, geographical and device contexts. The geographical context is modelled according to the location of the user, the region of interest, the extent of the region covered by the diffusion of the data, and the place where the information is processed. This characterization allows for the study of the different contextual configurations, and their impact on the design of mobile services. The framework is applied to maritime navigation.

Maritime GIS: From Monitoring to Simulation Systems

Combined research in the fields of Geographical Information Systems (GIS) and maritime systems has finally reached the point where paths should overlap and continue in better unison. This paper introduces methodological and experimental results of several marine-related GIS projects whose objectives are to develop spatial data models and computing architectures that favour the development of monitoring and decision-aid systems. The computing architectures developed integrate agent-based reasoning and distributed systems for the real-time monitoring, manipulation and simulation of maritime transportation systems.

A user context approach for adaptive and distributed GIS

The research presented in this paper introduces a user context approach for collaborative and adaptive Geographical Information System (GIS). The proposed model is part of a framework based on a multi-dimensional contextual approach that combines user, geographical and device contexts. The spatial properties of the GIS components categorize different configurations as a support for the derivation of user groups. The interfaces and functionalities offered by the adaptive GIS are generalized within each group, and derived from the interface usages. The spatial behaviors that reflect user experiences within a group favor collaborative exchanges. A prototype applied to maritime navigation validates the approach and the algorithms developed.

An Adaptive Interaction Architecture for Collaborative GIS

The research presented in this paper explores and models the interactions needed for the development of a collaborative and adaptive geographic information system (GIS). The proposed framework is based on a multidimensional contextual approach that differentiates between the user, the geographical, and the device contexts. The spatial distribution of the GIS functional components allows for the characterization of different geographical context configurations. These configurations act as a support for the derivation of user groups. The interfaces and functionalities offered by the adaptive GIS are modeled at the group level and derived from the interface usages and habits. The spatial behaviours that denote user experiences within a group are shared with other users within that group. Such an approach provides an adaptive and collaborative environment that favors exchanges and enriches the quality of services offered to the users acting in such a GIS environment. The framework was tested in the context of maritime navigation.
