利用GIS技术为土耳其进行天文选址
Astronomical Site Selection for Turkey Using GIS Techniques
摘要:
利用多标准决策分析结合地理信息系统和卫星图像对土耳其可能的观测站进行了选址,这反过来又减少了费用和时间,并提高了最终结果的准确性。在GIS系统中,对云量、数字高程模型、人工照明、可降水量、气溶胶光学厚度和风速等要素进行了研究。在MCDA的结论中,发现最合适的区域位于从西南到东北的带状交叉点,包括土耳其东南部的一个改道区域。因此,这些地区是我们未来现场测试的主要候选地点。除了这一主要成果,这项研究也被应用到主要的天文台网站的位置。由于没有为\textit{the best}设定目标,因此本研究的结果仅限于位置列表。因此,这份清单还需要通过现场测试进一步确认。已经提供了一笔国家资金,用于制作一个现场测试装置原型(测量天文和气象参数),该装置可能用于这一清单中的地点。
英文摘要:
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.
