The research conducted by the group STEAMER is focused on Web-based, spatial-temporal information systems, and more specifically, on processing spatial-temporal multimedia.
Our objective is to propose formalisms and methods permitting progression in the conceptualization, implementation and utilization of spatial-temporal multimedia information systems.
Considering the heterogeneous and mobile environments of these systems, we try to take into account:
- the diversity of users (in terms of their needs, priorities, levels of understanding, etc.),
- and its contexts of use (work stations, mobile phones, fixed or variable location, Web)
to offer a service or information adapted in terms of contents and presentation.
Our research is realized through the conceptualization and development of platforms and frameworks based on the possibilities of object-oriented knowledge systems and:
- structured or semi-structured formalisms (ontologies, objects),
- as well as Web technology (XML, Web services).
The application of our research takes place in the domain of Geographic Information Systems (interactive cartography, spatial analysis, mobile GIS, location-based services) and natural risks.
