Application of raster-based GIS techniques in the siting of landfills in Trabzon Province, Turkey: a case study

One of the most important steps in solid waste management is the selection of an appropriate landfill site. The site selection process requires the evaluation and analysis of several criteria. However, the traditional evaluation method is not sufficient for the site selection process. Geographical information system (GIS) technologies are effectively used in the process of site selection, which is a spatial problem. This article describes a raster GIS-based landfill site selection (LSS) method. This method utilizes a raster-based spatial database in which the factors affect the landfill site selection. The final product in this method is the cost surface map showing pixel-based values of the appropriate areas. Furthermore, this GIS-based LSS method was applied for the evaluation of two landfill sites in Trabzon Province in Turkey, for which the traditional evaluation method for site selection was used. The suitability values on the cost surface map of these two landfills have shown that these sites are not appropriate for a solid waste landfill. In conclusion, it was demonstrated that the method of raster GIS-based site selection gives more effective results than traditional methods.

A spatial multicriteria decision-making method for natural gas transmission pipeline routing

Abstract In accordance with current demands, the natural gas transmission pipeline (NGTP) is one of the most appropriate methods used in the distribution of existing reserves. Construction of long-distance pipelines requires large expenditures. Decreasing the time and cost of such construction and minimising environmental damage depend upon identifying the optimum routes from the onset of the project. Route determination is one of the most important steps in NGTP projects. The route determination process requires obtaining the existing graphic and non-graphic data from different institutions and organisations, as well as gathering, storing, querying and analysing non-existing data in an appropriate and efficient manner. Accessing the correct results rapidly by analysing such large data-sets can be achieved with spatial multicriteria decision-making technologies based on the geographic information system as an effective decision support tool. In this study, three methods were implemented for two NGTP projects of 103.60 and 60.89 km in length. At the end of this study, it was concluded that Spatial technique for order preference by similarity to ideal solution was the most effective of the three pipeline routing methods and that it could reduce project costs by approximately 21%.

Fire Analysis and Production of Fire Risk Maps: The Trabzon Experience

Today fire has an important place among the causes of loss of life and property. To intervene as soon as possible is of great importance, to eliminate or reduce the destructive effects of fires. Effectiveness of the intervention is directly linked with instant access to the fire, but the topography of the Black Sea region makes it difficult to intervene in fires on time due to poor access. Therefore, in order to fulfill the needs of the fire service and get fires under control, systems supported by information technologies can be used.

Municipal solid waste landfill site selection using Multi-Criteria Decision Making and GIS: case study of Bursa province

Rapid population growth, economic development and industrialization have created many problems related to municipal solid waste management (MSWM) in developing countries like Turkey. Solid waste disposal has become mandatory because of increasingly common factors such as global warming and contamination of water resources. In recent years, this situation has revealed the need for effective management of solid waste. Suitable site selection requires evaluation and analysis of multiplefactor. Therefore, it is very important that the design of landfill site selection take into account environmental, economical and sociologicalfactors. In order to do this, the Geographical Information System (GIS) used with Multi Criteria Decision Making (MCDM) techniques is a useful tool for creating a model. One such MCDM is the Spatial-integrated Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In this study, TOPSIS was applied to integrate environmental, economical and sociological sensitivity into determine alternative solid waste landfill sites for Bursa Province, Turkey. Using the data obtained by comparing the geo-statistics, six of the most suitable landfill areas were determined. In the final stage, as a result of this study, the Kayapa district was identified as the most suitable landfill area.

An alternative method for expropriation for lane-like projects in planned area: a case study from Trabzon in Turkey

This study focuses on the Tanjant Road in Trabzon, in which public authorities expropriated a lot of parcels together with buildings then destroyed all of them and then finally finished the road. If Tanjant road was opened in accordance 3194/18th article, contribution rate was to be 39%. It is seen that contribution rate to be curtailed from the adjusted cadastral parcels has fallen to 18% on 337 cadastral parcels after the expropriation for Tanjant road. If LR was applied, the road field to be expropriated would be met via the area acquired from the LR, thanks to contribution rate. In both practices, it is aimed that keeping arrangement area wide; the benefits and problems Tanjant road and article 18 have brought are distributed to a wide area. It is seen that expropriation costs are met free of charge in inner-city route with LR.

Procedure of Real Estate Acquisition by Foreigners in Turkey

Whether public, private, or something in between, property rights are a social, cultural, and economic base laying crucial groundwork for market economies. Within newly minted market economies, it becomes possible – even necessary – to recalibrate intuition towards land and other forms of property as commodities to be bought and sold in an international market (Tess, Commun Post-Commun Stud 37:213–239, 2004). Also, arising out of technological advances, coupled with the liberalization of capital markets worldwide that allow for efficient movement of capital between countries. Besides every nation, from past to present, has certain restrictions concerning the acquisition of land in the sense of absolute ownership by foreigners (Uzun and Yomralioglu, Foreigners in Turkey real estate acquisition: a review in the context of land management, chamber of surveying engineers of Turkey. In 11th scientific and technical conference of mapping, Ankara (in Turkish), 2007). However the removal of foreign ownership restrictions in many countries, a policy encouraged both by the Organization for Economic Cooperation and Development (OECD) and the European Union, made it easier for people to invest in foreign real estate markets (HPI, Housing Price Indices, the World wide overview of real estate prices in recent years of research division of the National Association of Realtors, Washington. Available from: http://www.realtor.org/sites/default/files/reports/2009/world-wide-overview-real-estate-prices-recent-years-2009-08.pdf. Accessed 22 Feb 2015, 2009). Turkey as a developing country, a member of OECD and candidate of EU, has made a series of arrangement in terms of foreign investment on residential property. Turkey is an attractive country in the international land market because of both its geography (with large coastal area and the Mediterranean climate) and its rapidly developing economy. Particularly in recent years, individuals and companies have started to be interested in purchasing real estate in Turkey and this combined with Turkey being accepted as an EU candidate country attention is being paid to the process of real estate purchase by non-Turkish nationals and companies (Uzun and Yavuz, European Union integration process of the Foreign nationals acquisition of immovable property in Turkey. In: 9th Turkey scientific and technical conference of mapping, Ankara (in Turkish), 2003). Since 2002, there has been renewed concern in Turkey about purchases of properties by foreign citizens, reflected in numerous amendments and cancellation decisions about such purchases by the Supreme Court and a number of state agencies. Despite the frequent changes, foreign direct investment (FDI) rose from just over US
