摘要

The total population of GPS-enabled location-based services (LBS) subscribers is constantly increasing. These GPS-enabled devices produce a wide range of media content (e.g., text/audio notes, pictures, or videos) enhanced by geo-tagged information. This fact poses a challenge regarding how to store and retrieve it and opens new research opportunities for visualizing this type of data. The overall aim of our research efforts is to develop novel approaches and methods for visualizing the content of these documents that will be placed in maps using GPS coordinates as well as to visualize the semantical, temporal, and spatial relations between the documents themselves. In this work, we concentrate on text documents and other data formats that could be transformed into text. We combined different visualization and interaction techniques, such as glyph-based techniques and visual clustering, to achieve our research aims. Our visualization tool, called GNV System (GeoNotes Visualization System), demonstrates the interplay of different interaction techniques and components as well as their functionality. It will be presented in this paper.
