Abstract
The focus of this dissertation lies in the research tradition of ESDA, which requires explicitly the existence of geographical attributes in the datasets, interactive visualization tools and dynamic graphics. In this study, I propose a new set of techniques for exploring O-D flow data and integrate it into an operational ESDA environment. These objectives are decomposed into the following components. First, an ESDA framework for O-D flow data is proposed by extending it from traditional ESDA frameworks. There are two important components in the framework: (1) Interactive Visualization; and (2) Data Structures. The former consists of a set of interactive visualization techniques and dynamic graphics (devices) for conducting exploration of O-D flow data. The later provides basic infrastructures for coordinating data and devices, and communicating between user-interface, data and devices (i.e., linking and brushing). Third, an easy-to-use prototype software system is implemented for the exploration and visualization of flows. Finally, the use of the 48 US state migration during 1995-200 demonstrated and tested the system and methods developed with real flow data in order to proof-of-concept result.
