Historico-Geographical Investigations into Reconstruction of Cities in East Asia, Utilizing Satellite Images

1.通过研究发现，美国在20世纪60年代拍摄的间谍卫星照片可以用于历史景观的重建，但在恶劣天气下拍摄的照片没有什么用处，因此希望以合理的成本使用高分辨率的卫星图像.一般来说，我们的方法更容易应用于农业用地，而不是城市化地区.今后，历史地理学必须发展其在景观研究中的应用.东亚历史城市遗址的考古发掘是解读照片的关键，而我们在遗址中发现遗迹。在中国古代城市方面，我们可以比以往的研究更详细地考察城市的布局，但我们发现，对于隋唐时期的长安和洛阳，我们没有得到更清晰的解释.由于庆州市无法获得清晰的照片，SPOT卫星影像应用于城市规划重建，但难以表现网格规划的细节，对于普约市的规划调查，SPOT卫星影像也不够好.解读这些照片，不可或缺的是实地考察。

1. For our research, we have found that the photographs of spy satellite taken by the UnitedStates in the 1960's are available for the reconstruction of historical landscape.But the photographs taken in bad weather are not useful, so it is expected the satellite images of high resolution are used by reasonable costs.2. Genrally speaking, our method is more easily adopted to farm land than urbanized area.Hrereafter hitorical geography has to develop the apllication to landscape research.3. Archaeological excavatin of sites of east asian historical cities give the key to the interpretation of the photographs, while we find the traces of ruins in the photographs.4. On the anciet cities in China, we could investigate the more details of layout than former studies.But we realized that Chang an and Luo yang in Sui and Tan dynasty were not interpretated clearly without more distinct photographs.5. As we could not get the clear photograph of Kyongju, satellite image of SPOT applied to the reconstruction of city plan.But it was difficult to represent the details of grid plan.Also for the investigation into the plan of Puyo, the photograph was not so good enough.6. Interpretating the photograpfs, it is indispensable to survey the sites.
