Importance of 3D Visualization for Land Use Planning, Construction and Management of the Karsiyaka Settlement Area (Izmir-Turkey)

摘要

Due to recent technological advances in 3D geographic information system (GIS); These 3D visualization technologies have been widely used in urban planning decisions, including: where to build, how to plan for natural disasters, the use of finite resources, how to incorporate sustainable practices, designing for growing populations and other engineering applications. In this study 3D GIS visualization technology is applied to Karsiyaka (Izmir) settlement area to show its applicability for the land use planning, construction and management. This study is carried out in four different stages: In the first stage; 1:25000 scale topographic maps and 1:1000 scale geological maps are digitised in GIS environment and their attribute tables are stored in the GIS databases. In the second stage; sub-surface of the study area was visualized using 3D technologies. This visualisation process is used to assist decision-making for land use planning. In the third stage; and useful soil class zonation maps are performed to be used in further studies. At last stage; after research at this site, the construction applications of Karsiyaka have been multiplied.
