In each factor of
disaster (from preparedness, prevention, response, and eventual recovery), all
require access to geographically referenced information and tools for making
available information relevant to the tasks at hand and in time. Geographic
Information and technologies (GI&T) are clearly and incontestably an
essential part of disaster management in all aspects and have been used
effectively at all scales. However, current GI&T specifically focus on Geospatial abstraction methods, more specifically on spatial data
acquisition, storage, update, query, representation and visualization. This frequently
leads to insufficient use of implicit knowledge and explicit knowledge as well
due to the lack of awareness of participants. So the question of what
information are quoted, and how to document, process and distribute valuable
information to responders effectively, remains an open research topic in crisis
management domain, and many other GIS application fields as well.
This paper proposes an
approach to extend traditional cartographic visualization to cartographic
process visualization by combining cognitive tools (ontology-based knowledge
management - concept maps) in the process of map generation in the context of
crisis management. Specifically, we focus on how the interactive maps can
automatically be generated based on a particular or given scenario by building
generating patterns and transferring mechanisms between visual representation
of formal knowledge and Geo-database through concept maps. The potential of
this approach is supposed to facilitate visual, manipulable, dynamic, and
analytical cognitive process in geographic visualization, thus to enhance
visual availability of complex phenomena or processes in a time strict
situation, and to support decision-making effectively.
In this paper,
Emergency Response of Environmental Pollution Event is designed as a
characteristic scenario background. Scenario is logically structured as formal
ontologies, graphically represented by concept maps. The scenario can be recomposed,
and/or recombined to form new knowledge in terms of multiple viewpoints of
users.
One of the main
challenges in this research is how interactive maps can be generated
automatically by bridging across concept maps. It can be addressed through encoding
semantic mapping between concept maps and interactive maps to build the
relationships of visual representation structures of particular problems and
geographic visualization patterns.
