Technical investigations for the reconstruction of historical landscapes with the aid of Geographic Information Systems

1.对9~13世纪土地利用和土地管理制度的发展进行了深入研究。<th><th>在两张图画地图上：奈良县的Nukatadera garan narabini jorizu和冈山县的Bicyunokuni Kayogun Hattorigozu。地图与近代景观的关系在本课题的前期研究中已进行了详细的讨论.利用地理信息系统对灌溉系统的分析表明，农业供水的发展在这两个时期之间发生了巨大的变化。考古发掘的结果进行了审查，在新确定的服部地区的Jori系统的关系。特别调查了最近发掘的一个庄园住宅考古遗址--戈肖遗址。利用地理信息系统重建了这两个地区的历史景观。他们还比较了景观的约克地区和中世纪的文件末日审判书。英国5.为了重建历史景观，尝试利用已公布的数字高程模型数据。然而，这些数据的分辨率是如此的不足，为这些目的，一些程序的插值在GRASS地理信息系统进行了尝试。这项研究结果的报告已经发表。它包括GISmap、DrawGrid和Shadeview的开发程序手册。

1. The development of land use and land administration system from the 9^<th> to 13^<th> centuries was intensively investigated. on two pictorial maps: Nukatadera garan narabini jorizu of the Nara prefecture and Bicyunokuni Kayogun Hattorigozu of the Okayama prefecture. The relationships of the maps and the recent landscapes were discussed in detail in the previous research of this topic.2. The analyses of irrigation systems with the aid of Geographic Information Systems revealed that the development of agricultural water supply was dramatically changed between the two periods.3. The results of archaeological excavations were examined in the relation of newly identified Jori system of the Hattori region. A recently excavated archaeological site of a manor house, Gosyo Site, was especially investigated.4. Historical landscapes of the two regions were reconstructed using Geographic Information Systems. They were also compared with the landscape of the York region and the Medieval document of Domesday Book. of England.5. For the purpose of reconstructing historical landscape, the data of published digital elevation model were tried to be used. However, the resolution of these data was so insufficient for such purposes that some programs of interpolation in a GRASS GIS were tried.6. The report of the results of this research was published. It includes the manuals of developed programs of GISmap, DrawGrid and Shadeview.
