标题： Astronomical Site Selection for Turkey Using GIS Techniques

摘要： 已在土耳其使用基于多准则决策分析（MCDA）与地理信息系统（GIS）及卫星影像相结合的方法完成了潜在天文台选址工作，这种方法减少了成本和时间，并提高了最终结果的准确性。 在GIS系统中研究了云层覆盖、数字高程模型、人造光源、可沉降水汽、气溶胶光学厚度和风速等图层。 根据MCDA的结论，最适合的区域被确定为一条从西南到东北延伸的地带，也包括土耳其东南部的一个偏移区域。 因此，这些区域是我们未来实地测试的主要候选地点。 除了这一主要成果外，本研究还应用于主要天文台选址点。 由于未为\textit{最好的}设定目标，本研究的结果局限于一个位置列表。 因此，该列表必须通过现场测试进一步确认。 一项国家级资助已授予制造一种现场测试单元原型（用于测量天文学和气象学参数），该单元可能用于此位置列表中。 显示英文摘要

摘要： 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 \textit{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.
