Transportation infrastructure is also strongly related to a number of sustainability concerns of primary policy relevance. Planners and engineers can use urban geology’s information on urban geologic environments as a scientific foundation for proper land use planning and transportation development. Such mapping can be categorized according to its scale, content, and purpose. This study uses Istanbul’s engineering geological mapping process as a case study. The Geographic Information System (GIS) was used to build the input layers (slope, topography, and lithology), which were then integrated to create engineering geological maps. A suitability map is used to display the results. The study area was thus divided into two categories: favorable and unfavorable. A spatial representation of intricate geological systems is provided by these segmentations. This study aimed to demonstrate a more thorough investigation of the target region in order to assess the imperatives that need the selection of places for building. Site-specific research, including in-situ and laboratory tests, should expand on the findings of this study in order to determine the necessary parameters for the constructions of greater significance.}, number={1}, publisher={Süleyman Demirel University}
