This study aims to analyze and visualize the spatial patterns of urban land use changes in Erbil City, Kurdistan, using remote sensing techniques. It quantifies the variations in land use classes over time by examining multi-date Landsat 5 TM imagery. The research utilizes supervised classification and accuracy assessment methods to measure the extent of land cover changes and their implications for urban planning and resource management.
Chapter one introduces the study, outlining its significance, the research problem, the aim, research question, and the organization of the thesis. Chapter two delves into the literature review, exploring the historical application of remote sensing, identifying urban land use change, urban change detection approaches, and methods of digital image processing of satellite images including image classification and accuracy assessment. Chapter three focuses on the data and methodology, providing a description of the study area, the data used, and the methods employed. Chapter four presents the results and discussion, showcasing the image pre-processing, supervised classification, reclassification, post-classification change detection techniques, and accuracy assessment results. Finally, Chapter five concludes the study, highlighting limitations, contributions to the body of knowledge, and recommendations for future research.
This research focuses on urban land use change, remote sensing, image classification, change detection, accuracy assessment, urban planning, and resource management. It utilizes Landsat 5 TM imagery, supervised classification, maximum likelihood classifier, and confusion matrix techniques to analyze and quantify the spatial patterns of urban expansion in Erbil City, Kurdistan.
The study aims to analyze and visualize spatial patterns of urban land use changes in Erbil City, Kurdistan, and to quantify these variations using remote sensing tools over the period from 1987 to 2011.
The research utilized multi-date Landsat 5 TM satellite imagery processed with ERDAS 9.1 software, employing supervised classification (Maximum Likelihood classifier).
The built-up area increased from 3,975.66 hectares in 1987 to 6,123.7 hectares in 2000, and significantly jumped to 12,755.1 hectares by 2011.
Open land and vegetation classes experienced the most significant decline as they were converted into urban built-up areas during the rapid expansion of the city.
The accuracy was tested using confusion matrices and the Kappa coefficient, achieving high overall accuracy rates between 94.29% and 96.43% for the different years.
The findings provide valuable spatio-temporal information necessary for sustainable planning and the management of urban resources in the rapidly growing Kurdistan region.
