ABSTRACT This paper presents a system for overlaying D GIS data information such as 3D buildings onto a 2D physical urban map. We
propose a map recognition framework by analysis of distribution of local intersections in order to recognize the area of the
physical map from a whole map. The retrieval of the geographical area described by the physical map is based on a hashing
scheme, which is called LLAH. In the results, we will show some applications augmenting additional information on the map.

    ABSTRACT: Geovisualization has traditionally played a critical role in analysis and decision-making, but recent developments have also brought a revolution in widespread online access to geographic data and integration tools, particularly for map-based interfaces. This next generation of geovisualization applications is often characterized by high interactivity and strong end-user participation in both development and use. Building the most effective tools to support user-centered geographic visualization faces a significant challenge, though: very little is known about how people interact with maps. To date, map use research has typically focused on higher order use goals or cognitive interpretations of static map representations. Our research employs Human-Computer Interaction approaches in order to investigate user behaviors that contribute to interactive map use and understanding. This paper describes our approach to studying geovisualization interaction and presents our pilot user studies and initial interaction model. By building a better understanding of how people interact with map interfaces, we will be able to design better user-centered geographic visualizations and learn how to best customize these applications to specific user groups.
