Towards A Spatial Model Of Rurality, Gillian Avruskin Aug 2000

Towards A Spatial Model Of Rurality, Gillian Avruskin

Electronic Theses and Dissertations

The term rural is used to describe people, places, traditions, and spaces. It is often employed as a setting for study as well as an object of study. People’s perceptions of rural are confused and differ considerably. For over a century researchers have attempted to define more precisely this term using social, economic, and or ecological components. However, problems of interpreting official definitions and measurements exist. These definitions require extensions in order to capture a more objective meaning of the word. This thesis presents the foundations of a new approach to measuring and defining rurality. A spatial based approach is …


Image-Based Change Detection Using An Integrated Spatiotemporal Gazetteer, Georgios Mountrakis Aug 2000

Image-Based Change Detection Using An Integrated Spatiotemporal Gazetteer, Georgios Mountrakis

Electronic Theses and Dissertations

This thesis addresses image-based change detection. Motivation was provided by the lack of algorithms that incorporate in their solution diverse types of pre-existing and complementary information and have the ability to interact with a spatiotemporal environment. The main differentiation with our approach is that we develop our algorithm within an integrated spatiotemporal environment and we make use of all change evidence that might exist within that environment. In addition, a change resolution model is developed that will distinguish meaningful changes based on user requirements. A model for change is proposed that establishes a general framework for the incorporation of image …
