GeoGuide: An Interactive Guidance Approach for Spatial Data

Spatial data is becoming increasingly available in various domains such as transportation and social science. Discovering patterns and trends in this data provides improved insights for planning and decision making for smart city management, disaster management and other applications. However, exploratory analysis of spatial data is a challenge due to its huge size of spatial data. It is often unclear for the analyst what to see next during an analysis process, i.e., lack of guidance. To tackle this challenge, we develop GeoGuide, an interactive guidance approach for spatial data. GeoGuide captures the implicit feedback of analysts and exploits it to highlight potentially interesting analysis options. We discuss some real-world applications of GeoGuide. We also show the usability of the framework in a comparative user study.
