A semi-automated display for geotagged text

The changing dynamic of crisis management suggests that we should be leveraging social media and accessible geotagged text data to assist with making emergency evacuations more effective and increasing the efficiency of emergency first responders. This chapter presents a preliminary visualization tool for automatically clustering geotagged text data, and visualizing such data contextually, graphically, and geographically. Such a tool could be used to allow emergency management personnel to quickly assess the scope and location of a current crisis, and to quickly summarize the state of affairs. Discussion herein includes details about the clustering algorithm, design and implementation of the visualization, and ideas for improving the utility for use in a variety of circumstances.
