Geographical information systems based microzonation map of Eskişehir downtown area

Kolat, Çağıl
The purpose of this study is to prepare a geotechnical microzonation map regarding the suitability of the residential areas in Eskisehir downtown area. In order to obtain the microzonation map, Geographical Information Systems (GIS) based Multicriteria Decision Analysis (MCDA) is used. For this analysis, the slope, flood susceptibility, soil, depth to groundwater table, swelling potential and liquefaction potential layers are prepared. The weight values to the layers and rank values to the classes of each layer are assigned by applying Simple Additive Weighting (SAW) and Analytical Hierarchical Process (AHP) methods. Two geotechnical microzonation maps are obtained as outputs of these methods. The study area is categorized into three different zones regarding the foundation suitability of residential areas as: (1) Areas suitable for settlement; (2) Provisional settlement areas; (3) Areas requiring detailed geotechnical investigations. The maps prepared using SAW and AHP methods are found to be consistent with each other. The geotechnical microzonation map prepared using AHP method is recommended as the final map of the study area.


GIS as a tool for analyzing legal struggles: an analysis of lawsuits filed by the chamber of city planners Ankara, Turkey.
Yalçınkaya, Özle; Severcan, Yücel Can; Department of Geodetic and Geographical Information Technologies (2019)
Examination of past urban planning practices, reveals that they are used improperly by decision makers, often ignoring the social and environmental impacts of planning processes and the planning principles. That is why professional chambers, non-governmental organizations (NGOs) and other public organizations (like local municipalities) strive to monitor the urban and regional plans and their implementations. In order to stop the implementation of the plan decisions/actions, which are taught to have negativ...
Analyzing Green/Open Space Accessibility by Using GIS. Case Study of Northern Cyprus Cities
Kara, Can; Akcit, Nuhcan (2015-03-19)
It is well known that green spaces are vital for increasing the quality of life within the urban environment. World Health Organization states that it should be 9 square meters per person at least. European Environment Agency defines that 5000 square meters of green space should be accessible within 300 meters distance from households. Green structure in Northern Cyprus is not sufficient and effective in this manner. In Northern Cyprus, they have neglected the urban planning process and they have started to...
GIS-based stochastic modeling of physical accessibility using GPS-based floating car data and Monte Carlo simulation
Ertugay, Kivanc; Duzgun, Sebnem (Informa UK Limited, 2011-01-01)
The term physical accessibility has long been used by geographers, economists, and urban planners and reflects the relative ease of access to/from several urban/rural services by considering the traveling costs. Numerous accessibility measures, ranging from simple to sophisticated, can be observed in the geographical information systems (GIS)-based accessibility modeling literature. However, these measures are generally calculated from a constant catchment boundary (a most likely or average catchment bounda...
An exact and a heuristic approach for the transportation-p-facility location problem
Das, Soumen Kumar; Roy, Sankar Kumar; Weber, Gerhard Wilhelm (Springer Science and Business Media LLC, 2020-01-30)
The delineation of the transportation network is a strategic issue for all over the place. The problem of locating new facilities among several existing facilities and minimizing the total transportation cost are the main topics of the location network system. This paper addresses the transportation-p-facility location problem (T-p-FLP) which makes a connection between the facility location problem and the transportation problem, where p corresponds to the number of facilities. The T-p-FLP is a generalizati...
Preparation of a geotechnical microzonation model using Geographical Information Systems based on Multicriteria Decision Analysis
Kolat, Çağıl; AYDAY, Can; Süzen, Mehmet Lütfi (2006-11-03)
The purpose of this study is to develop a geotechnical microzonation model using Geographical Information Systems (GIS) based on Multicriteria Decision Analysis (MCDA). As study area, the Eskisehir downtown area has been chosen. Eskisehir is one of the most rapidly growing cities in central Turkey. The model inputs include slope, flood susceptibility, soil, depth to groundwater table, swelling potential, and liquefaction potential. The weight and rank values are assigned to the layers and to the classes of ...
