Geosimulation And Multicriteria Modelling Of Residential Land Development In The City Of Tehran: A Comparative Analysis Of Global And Local Models, Hossein Hosseini

Electronic Thesis and Dissertation Repository

Conventional models for simulating land-use patterns are insufficient in addressing complex dynamics of urban systems. A new generation of urban models, inspired by research on cellular automata and multi-agent systems, has been proposed to address the drawbacks of conventional modelling. This new generation of urban models is called geosimulation. Geosimulation attempts to model macro-scale patterns using micro-scale urban entities such as vehicles, homeowners, and households. The urban entities are represented by agents in the geosimulation modelling. Each type of agents has different preferences and priorities and shows different behaviours. In the land-use modelling context, the behaviour of agents is their …

Quality Assessment Of The Canadian Openstreetmap Road Networks, Hongyu Zhang

Electronic Thesis and Dissertation Repository

Volunteered geographic information (VGI) has been applied in many fields such as participatory planning, humanitarian relief and crisis management because of its cost-effectiveness. However, coverage and accuracy of VGI cannot be guaranteed. OpenStreetMap (OSM) is a popular VGI platform that allows users to create or edit maps using GPS-enabled devices or aerial imageries. The issue of geospatial data quality in OSM has become a trending research topic because of the large size of the dataset and the multiple channels of data access. The objective of this study is to examine the overall reliability of the Canadian OSM data. A systematic …

Exploring Factors Influencing Children's Use Of A Free Recreation Access Pass: Does Geography Matter?, Joannah M. Campbell

Electronic Thesis and Dissertation Repository

Only a small proportion of Canadian children achieve the recommend daily minimum amount of moderate-vigorous physical activity (PA). The Grade 5 ACT-i-Pass (G5AP) program in London, Ontario offers fifth-grade children a free access pass to multiple PA opportunities at recreation facilities for an entire school year. This thesis used a mixed-methods approach to examine barriers and enablers to children’s use of those PA opportunities. In-depth interviews with recreation service providers afforded an understanding of potential factors influencing pass use. Surveys of child participants and their parents provided data on participant demographics, parental and peer support, and pass usage. Spatial analysis …
