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

1.在我们的研究中，我们发现美国在20世纪60年代拍摄的S间谍卫星照片可以用于重建历史景观，但在恶劣天气下拍摄的照片没有用，因此预计高分辨率的卫星图像将以合理的成本使用。总体而言，我们的方法比城市化地区更容易被用来耕种土地，因此，历史地理学必须发展在景观研究中的应用。对东亚历史名城遗址的考古发掘为解读照片提供了关键，而我们在照片中发现了废墟的痕迹。对中国的古城，我们可以比以往的研究更详细地考察布局，但我们意识到，如果没有更清晰的照片，我们就无法清楚地解读隋唐时期的长安和罗扬。由于无法获得庆州的清晰照片，SPOT卫星图像应用于城市规划的重建，但很难再现格状平面的细节，而且对于普约平面的调查，照片也不够好。为了诠释照片，勘察遗址是必不可少的。

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.
