Computer Science—the theory, representation, processing, communication and use of information—is fundamentally transforming every aspect of human endeavor. The Department of Computer Science at Iowa State University advances computational and information sciences through; 1. educational and research programs within and beyond the university; 2. active engagement to help define national and international research, and 3. educational agendas, and sustained commitment to graduating leaders for academia, industry and government.

History
The Computer Science Department was officially established in 1969, with Robert Stewart serving as the founding Department Chair. Faculty were composed of joint appointments with Mathematics, Statistics, and Electrical Engineering. In 1969, the building which now houses the Computer Science department, then simply called the Computer Science building, was completed. Later it was named Atanasoff Hall. Throughout the 1980s to present, the department expanded and developed its teaching and research agendas to cover many areas of computing.

Abstract

The use of location-based applications has increased among common users and field agencies. Geographical information systems have benefitted organizations of all sizes and almost every industry. Studies have indicated that the user's spatial ability plays an important role in how the users interact with the software. Investigators have found that spatial ability is composed of five components such as visualization, speeded rotation, closure speed, closure flexibility and perceptual speed. In order to scientifically study individual differences in spatial ability, various visualizations and views of a geographic area that closely resembles user's perception needs to be developed. Object-oriented approach of maps provides a self-contained representation of the features in a geographical region. With the help of such a representation, various usability features and visualizations can be developed to study individual differences in spatial ability.

This thesis describes an object-oriented approach to representing maps and building maps software on top of that. It describes the data model, the development of the maps software and the pilot conducted to evaluate usability features developed.
