Social media allows people to receive, engage in, and share weather information. Users of the social media platform Twitter actively share weather content via tweets, which researchers can acquire through an Application Programming Interface (API). APIs return tweet content, as well as temporal and spatial characteristics (latitude and longitude coordinates). Tweets can then be mapped and studied spatiotemporally through Geographic Information System (GIS) software. For this work, I compared how tweets spread (“diffuse”) over space and time during two natural hazard events in the United States. The first case study is a winter weather event that The Weather Channel named …

Integrating Social Media In The Development Of A Special Event Population Dynamics Model, Kelly Michelle Sims
Masters Theses
With society’s increasing participation in social media, scientists now have access to new sources of data that reflect our daily activities in space and in time. Such data are plentiful and, more notably, at an unprecedented granular level. The ability for users to capture and express their geolocation through their phones’ global positioning system (GPS) or through a particular location’s hashtag or Facebook Page provides a great opportunity for modeling spatiotemporal population dynamics. High resolution population models and databases for episodic special events can be extremely useful for enhancing emergency management and response. This research assesses the feasibility of improving …

Geospatial Data Accessibility In Web 2.0 Environments, Sara Helen Mcnamee
Masters Theses
Geographically referenced data is becoming a robust source of information because the use of place-based relevance searching is being employed as a popular form of information access and dispersal. To address this trend, the researcher conducted a study on the usability of the USA National Phenology Network (http://www.usanpn.org/), engaging 6 volunteer participants structured usability test of the USANPN mapping application. The participants were asked to complete two tasks, and data was collected both during (in the form of a think aloud exercise) and after the test (in the form of an exit interview). From the data collected, the researcher aimed …
