Assessment of temperature and humidity of urban building using high-spatial resolution image world view 3 / Muhammad Daniel Haziq Mohamad Rosdi

The urban area, which consist a variety of building material has an immediate effect on the microclimate and on human comfort, which in turn has an effect on the global climate and heat island phenomenon. The extensive use of concrete and other several types of building material such as wooden and steel in urban area contributes to the heat island phenomenon, which indeed has a negative impact on thermal comfort. Besides, the global climate change is being amplified by an increase in humidity and temperature in urban area. Therefore, this research aims to assess the relationship between temperature and humidity of urban building materials with environmental in Sri Petaling, Selangor using high-spatial resolution image, Worldview 3. The discrimination of urban building among landuse lancover (LULC) utilized Support Vector Machine (SVM) classifier via object-based image analysis (OBIA) method. There are three (3) objectives have been determined; i) to classify the building materials, and. ii) to identify the temperature and humidity of different building materials, and. iii) to assess the relationship between temperature and humidity of urban building materials with surrounding environment. The expected outcome of this study is a map of different urban building materials and the impact of surrounding environment towards temperature and humidity of building materials. Consequently, this study will assist in reducing the effect of urban heat island (UHI) and benefited to Ministry of Health and municipal council in urban planning management especially in evaluating the climate effects of building materials towards surrounding environment.
