This paper is a report on the planning, design, and implementation of the Hopi Horizon Analysis project. The project client is Dr. Wesley Bernardini, a professor of Sociology and Anthropology at the University of Redlands. Dr. Bernardini wanted to know in what ways the visual properties of horizons influenced how the Hopi culture retained knowledge of distant places as they migrated to new locations. This project developed a method for ranking the visual significance of mountain peaks along an observer’s visual horizon using the Douglas-Peucker line simplification algorithm. The project implementation involved the design and construction of a geodatabase, the development of custom geoprocessing tools, and the implementation of a technique for visualizing the changes in peak significance over time.
