Abstract
Throughout the past few decades, Dubai City has witnessed massive growth in its urban area and infrastructure facilities. The discovery of oil and gas in the Emirate significantly played a role for such a rapid growth. Given this fact and the short time-period for such an expansion, it is crucial to develop an understanding of the patterns of the development in the City, where policy-makers, researchers, and concerned authorities would gain better vision and strategy for the future. Recent advances in satellite imagery in terms of improved spatial and temporal resolutions are allowing for efficient identification of change patterns and the prediction of areas of growth. This study aims to quantify and analyse the spatial–temporal urbanization that took place in Dubai City throughout the past decades (specifically from early 1970’s until 2015). Multi temporal satellite images with various geometric and radiometric resolutions will be utilized for this purpose. The suggested methodology consists of a sequence of image processing techniques that include supervised and unsupervised classification. Subsequently, the classified images were utilized to quantify the urbanization of the City. The results show that since 1970, the urbanization and population have been dramatically increased by 5 and 12 times respectively. The resulting trend can be potentially used to evaluate the consequences of massive urban development, such as City infrastructure, water, environmental and the social impact.
Highlights
Over the last few decades, the United Arab Emirates and Dubai City in particular have witnessed significant economic growth since the oil discovery in the region
Refereeing to literature and previous studies,ithas been found that Geographic Information System (GIS) and Remote Sensing (RS) techniques were not used efficiently for change detection and urban development for the study area under consideration
The Annual Urban Spatial Expansion Index (AUSEI) would describe the temporal changes of Dubai in terms of its annual urbanization growth rate
Summary
Over the last few decades, the United Arab Emirates and Dubai City in particular have witnessed significant economic growth since the oil discovery in the region. Such a growth resulted in a rapid urbanization across the City, where a lot of residential, commercial, sports and tourism projects have been implemented. This expansion can be observed by many of the mega scale world’s landmarks such as Burj Khalifa (the tallest building in the world), Dubai Mall (the largest mall in the world by the total area), and Miracle Garden (the world's largest natural flower garden). The main objectives of this research are as follow:
