ÖZÜlkemizde arazi ve arsa düzenlemesi çalışmalarında alansal bazda eşitlik sağlanarak uygulamalar yapılmaktadır. Uygulamaların bu şekilde yapılması pek çok problemlere neden olmakta ve vatandaşlara adaletsiz dağıtımdan kaynaklı haksızlıklar yaşatılmaktadır. Özellikle imar uygulamalarındaki alan esaslı çalışmaların düzenlenerek değer esaslı çalışmalara dönüştürülmesi bu tür problemleri ortadan kaldıracaktır. İyi bir değerleme işlemi, taşınmaz değerine etki eden genel ve özel faktörlerin değerleme işlemine katılması ile mümkündür. Taşınmazın değerini etkileyen bu faktörlerin her parsele aynı oranda etkilemeyeceği aşikârdır. Dolayısıyla her bir etmen için, ağırlık katsayılarının belirlenmesi zorunluluğu ortaya çıkmaktadır. Bu çalışmada imar uygulanmasında taşınmazın önceki ve sonraki değerleri elde edilmek istenmiştir. Değeri etkileyen faktörler uygulama öncesi ve sonrasındaki duruma göre ayrı ayrı ele alınmış ve Analitik Hiyerarşi Prosesi (AHP) yöntemine göre ağırlıkları belirlenmiştir. Bu ağırlıklardan faydalanarak konumsal faktörler, mesafelere göre puanlandırılarak hem kadastro parsellerinin hem de imar parsellerinin faktör değerleri elde edilmiştir. Bu faktör değerlerinin öncesi ve sonrası durum toplamları eşitlenmiştir. Taşınmazlar AHP değerli dağıtıma uygun hale getirilmiştir. Çalışmanın başarısını belirlemek için sonuçlar yürürlükteki uygulama ile karşılaştırılmıştır.Anahtar Kelimeler: Analitik Hiyerarşi Prosesi, imar, eşdeğerlilik esaslı arazi ve arsa düzenlemesi, değer USE OF ANALYTIC HIERARCHY PROCESS IN EQUIVALENCE BASED ARRANGING LANDS AND PLOTS ABSTRACTIn our country, plot and land management studies are being made by providing equality on the areal basis. The application in this manner causes many problems and the citizens are subjected to injustice due to field based distribution. Particularly, zoning practice will abolish such problems field-based studies to be transformed in to value-based studies. A good valuation process, general and specific valuation factors that affect the value of the real estate, it is possible to take part in the process. It is obvious that these factors affecting the value of the real estate will not affect each parcel in the same way. Therefore, for each factor, the necessity of determining the weight coefficients arises. In this study, in the implementation of zoning the values previous and next of the real estate is wanted to be obtained. Factors of the value affecting were handled separately according to the situation before and after the application and their weights were determined by the Analytic Hierarchy Process (AHP) method. Spatial factors using the specified weights were scored by distance. Factor values of both cadastral and reconstruction plots have been obtained. The pre-and post-state totals of these factor values were equalized. The real estates have been made available for AHP valued distribution. The results were compared with the current practice to determine the success of the work.

“…Since most of these layers were publicly available they were acquired and studied with standard procedures. These layers constitute the essential selection criteria to find the best possible observatory sites before in-situ detailed selection studies (Koç-San et al, 2013). Therefore, since the ultimate aim of using above layers is to find a location where Z-values (i.e.…”

A site selection of potential observatory locations in Turkey have been carried out by using Multi-Criteria Decision Analysis (MCDA) coupled with Geographical Information Systems (GIS) and satellite imagery which in turn reduced cost and time and increased the accuracy of the final outcome. The layers of cloud cover, digital elevation model, artificial lights, precipitable water vapor, aerosol optical thickness and wind speed were studied in the GIS system. In conclusion of MCDA, the most suitable regions were found to be located in a strip crossing from southwest to northeast including also a diverted region in southeast of Turkey. These regions are thus our prime candidate locations for future on-site testing. In addition to this major outcome, this study has also been applied to locations of major observatories sites.Since no goal is set for the best, the results of this study is limited with a list of positions. Therefore, the list has to be further confirmed with on-site tests. A national funding has been awarded to produce a prototype of an on-site test unit (to measure both astronomical and meteorological parameters) which might be used in this list of locations.

“…Using GIS and AHP has been proven effective in analyzing natural hazards such as landslides and floods (Gamper et al 2006; Fernández and Lutz 2010) and environmental studies (Ying et al 2007; Rahman et al 2014). The GIS-based and analytic hierarchy process has been applied by Koc-San et al (2013) to choose a suitable site for an astronomical observatory. The same technique was used in Konya, Turkey, by Uyan (2013) to select the best site for solar farms.…”

Watershed vulnerability and the characterization of potential risk are important inputs for decision support tools in assessing watershed health. Most previous studies have focused on the assessment of the environmental risk using physicochemical properties of surface water and mathematical models to predict the health of a watershed. Here, we present a new methodology for evaluating watershed vulnerability using the analytic hierarchy process (AHP) and weighted overlay analysis. The new methodology provides an inexpensive approach for assessing areas that need more investigation based on known factors such hydrogeological, geological, and climate parameters without the need for site-specific physicochemical data. The proposed method was implemented using six main factors that influence water quality: land use, soil type, precipitation, slope, depth to groundwater, and bedrock type. Vulnerability was predicted for ten sub-watersheds within the Eagle Creek Watershed in Indiana using publicly available data input into geographic information system. Combination of watershed susceptibility assessment and GIS spatial analysis tools was used to produce the maps that show the susceptible zones within a watershed. A comparison of the resulting vulnerability estimates showed the expected significant positive correlations with measurements of nitrate, phosphate, temperature, and electrical conductivity. Likewise, the vulnerability estimates negatively correlated with dissolved oxygen and E. coli. Furthermore, the validation of the proposed approach revealed that the areas predicted to have high vulnerability did have lower water quality indices; the results showed a high negative correlation (r2 = 0.77, p < 0.05) between water quality index (WQI) and vulnerability which strongly suggests this method can be used successfully to assess a watershed’s susceptibility.
