Conference paper Open Access
The availability of user-generated geographic datasets offers the possibility of exploring the phenomenon “place”. In recent years researchers started some attempts to derive more information about places from the content of geo-tagged social media platforms, e.g., Twitter and Flickr. For the communicating of the analysis results, visualization is essential, but there is less knowledge available about platial visualizations. After a short review of the literature about the extraction, approaches of analysis, and visualization of places, we will present our two methods. Based on a specific use case we will utilize density based clustering and aggregation in grid cells to demonstrate quantitative information visualization of the diversity of a place on multiple scales with pie charts.
