Abstract 3D geographic information system software’s (GIS) are widely used in engineering geology applications. This study was performed in the Karsiyaka settlement area for the preparation of engineering geological maps and evaluation of geological structures. Firstly, topographic maps digitized with Arcview GIS 3.2. Engineering geological maps were prepared using site works and digitized with the Rockworks 2006 programme and later stored in GIS-based computer systems. 3D modelling analysis and assessment using a geotechnical database is important to assist decision-making for land use and metro subway line planning, construction site selection, selection of water sources, etc. In this respect, the sub-surface of the study area is fully 3D visualized and useful soil class zonation maps for different depths maps are performed to be used in further studies. At last, after research at this site, the construction applications of Karsiyaka have multiplied. Keywords Geotechnical database . Engineering geological maps . Geographic information system (GIS) .

Introduction In the last decade, with the advances in computer technologies, GIS is frequently used for spatial data management and manipulation. A geo-environmental evaluation for urban landuse planning often requires a large amount of spatial

information. GIS is a powerful tool by evaluation of huge numbers of data for the geo-scientific evaluation in performing of such analyses on very large areas in very short times. An important feature of a GIS is the ability to generate new information by integrating the existing diverse datasets sharing a compatible spatial referencing system. Although GIS technology has been widely used to assess natural geological hazards, groundwater vulnerability assessment and site selection for waste disposal, studies which are related with geo-environmental evaluation for urban land-use planning (Dai et al. 2001). 3D modelling technology achieves rapid development, and all kinds of modelling theories and methods are constantly put forward. Planners, urban designers, landscape architects and other planning professionals use computerized visualization techniques to encourage participation by the public. Many of the techniques they employ can be incorporated into a GIS (Meenar and Ambrus 2006). Surface and subsurface unified models have been studied by many researchers (Culshaw 2005; Wang 2006; Breunig and Zlatanova 2006; Abdul Rahman and Pilouk 2008). Their research is based on enhanced forms of the 3D Formal Data Structure (3D FDS) for 3D spatial data for both surface and subsurface 3D o
