A User-centric Approach for Interactive Visualization and Mapping of Geo-sensor Data

Sensor network applications collect and use sensor data from distributed sensor networks and databases. These real-time and time series sensor data are very useful for many location-based systems that manage and browse various kinds of personal spatial information such as digital photograph, travel diary and so on. Such location-based system for personal use requires a user-centric framework that can support intuitive query request and direct sensor data mapping. This paper proposes a user-centric approach for interactive visualization and mapping of geographically distributed sensor data. The overview of the prototype system that we are developing is briefly described. Our approach generates a query for distributed sensor databases based on user´s track log. This method produces understandable information from collected sensor data based on GIS (geographic information system) methods.
