Land Use Interactions Drive Southwestern Ontario Stream Nutrient Concentrations, Renee L. Lazor

Electronic Thesis and Dissertation Repository

Human activities have transformed the landscape and altered natural habitats through intensive land uses including agriculture and urbanization. Identifying land use drivers of tributary nutrient concentrations and describing the magnitude and direction of their relationship are critical activities to improvement management of water quality in basins draining into the Great Lakes. The overarching goal of my thesis was to quantify the cumulative influence of spatial patterns in land use and land cover on variation of nutrient concentrations in tributaries of the Great Lakes. Biweekly water chemistry samples were collected in 29 streams located in southern Ontario between May and November, …

A Positive Latitude - Georeferencing And Archives, Tom Belton

Western Libraries Presentations

A presentation regarding a proposed research agenda to determine the advantages and feasibility of using georeferencing and maps to provide access to, or visualize, resources in archival institutions and databases.

Multivariate Spatial Visualization Using Geoicons And Image Charts, Bo Shan

Electronic Thesis and Dissertation Repository

Spatial databases are growing in size and complexity, yet current visual data mining methods are challenged when it comes to multivariate spatial data. The specific research question addressed in this thesis is: how can spatial multivariate data be effectively visualized using an icon based non-fused co-visualization approach? The thesis presents a Python based design and implementation of a visualization program termed GeoIcon Viewer. The program incorporates two different visualization methods: GeoIcon Image Map and Region-of-Interest Image Layers Chart. The GeoIcon Image Map technique uses an icon to co-visualize up to nine attributes at a single location. The Region-of-Interest Image …

Analytic Network Process (Anp) For Housing Quality Evaluation: A Case Study In Ghana, Lucia Kafui Hussey

Electronic Thesis and Dissertation Repository

Quality of housing is crucial to an individual's quality of life as it is known to affect human health and well-being. Several studies have employed different methods to assess housing quality. These methods, however, failed to account for the interdependence among the factors (criteria) used for evaluating the quality of housing. This thesis proposes an Analytic Network Process (ANP)-based framework, integrated into Geographic Information Systems (GIS), to assess housing quality. ANP is a multicriteria analysis method. It provides a tool for identifying the relative importance of all the elements (criteria) influencing a goal of decision/evaluation problem (e.g., the problem of …

Examining The Influence Of Environmental Opportunities And Exposures On Children's Sleep Duration, Leanne B. Mcintosh

Electronic Thesis and Dissertation Repository

This research aims to fill a void in knowledge on how certain characteristics of the built and natural environments may impact children’s sleep duration. Data was collected on a sample of 614 children (aged 9-14 years) drawn from 22 elementary schools throughout the City of London, Ontario, Canada. Participants completed the STEAM (Spatial Temporal Environmental Activity Monitoring) protocol which involved completion of a survey, daily activity diary, and tracking the time they spent in different environments with a portable Global Position System. This thesis incorporates an innovative analytical approach which uses two Geographic Information System techniques to examine if and …

Automated Building Information Extraction And Evaluation From High-Resolution Remotely Sensed Data, Chuiqing Zeng

Electronic Thesis and Dissertation Repository

The two-dimensional (2D) footprints and three-dimensional (3D) structures of buildings are of great importance to city planning, natural disaster management, and virtual environmental simulation. As traditional manual methodologies for collecting 2D and 3D building information are often both time consuming and costly, automated methods are required for efficient large area mapping. It is challenging to extract building information from remotely sensed data, considering the complex nature of urban environments and their associated intricate building structures.

Most 2D evaluation methods are focused on classification accuracy, while other dimensions of extraction accuracy are ignored. To assess 2D building extraction methods, a multi-criteria …

Examining Children's Perceptions And Use Of Their Neighbourhood Built Environments: A Novel Participatory Mapping Approach, Stephen Fitzpatrick

Electronic Thesis and Dissertation Repository

This thesis uses a mixed methods approach to contribute towards a more complete understanding of the relationship between the built environment and children’s active school travel. It is argued that active travel –human powered transportation – to and from school provides regular physical activity that can help reverse rising rates of overweight or obese Canadian children. The built environment of a child’s school neighbourhood has been shown to influence travel decisions. To achieve higher rates of children’s active travel, a comprehensive understanding of the built environment is required.

This study uses child-led perceptual mapping (CLPM) and GIS analysis in a …
