Development of an integrated spatial information system for social archaeology enabling preservation of intangible academic knowledge : A case study in Northeast Thailand

这是2000至2002财政年度题为“通过时间序列空间信息系统了解过去和现在：泰国东北部定居的连续性和不连续性”的前一个项目的第二阶段项目。主要活动和成果如下：1.关于定居点连续性和不连续性的数据库（1）20世纪50年代的约350幅地形图和20世纪80年代的约100幅地形图作为数字化图像文件存档到泰国东北部村庄信息系统EcoNETVIS：生态历史中。大约800张1950年代的航空照片在确定其地理参考后仍在逐步存档。（2）更新了室萨克拉·瓦利布霍塔马调查的EcoNETVIS中约1 000个地点的地理参考和学术信息。Walailak Songsiri在日本期间积极参与了这项工作。2.改进EcoNETVIS：在EcoNETVIS网页中引入了“网站查看器”页面 ...更多信息 3.开发支持实地调查的系统：开发了使用笔记本电脑和全球定位系统天线的原型实地工具。它支持网站导航和学术信息和基本地理图像的浏览。几次实地实验证明了它在轻松准确地导航到古代遗址方面的有效性，即使是那些几乎已经消失的遗址。在此基础上，进行了逐步的改进，今后还将继续进行实际应用的开发。上述2、3的开发是重要的方法，通过这些方法，我们的研究结果可以应用于需要实地调查的人文学科领域。提供当地研究人员和学生能够获得基本学术材料的方法是该项目能够为下一代保存无形学术知识的一种方式。少

This is a second-phase project continuing from the previous project titled "Past and present through a time-series spatial information system : Continuity and discontinuity of settlement in Northeast Thailand" from 2000 to 2002 fiscal year. Major activities and results are as follows.1.Database on continuity and discontinuity of settlement(1)About 350 topographic maps from the 1950s and about 100 topographic maps from the 1980s were archived as digitized image files into the EcoNETVIS, Northeast Thailand Village Information System : Eco-history. About 800 aerial photos from the 1950s are still gradually being archived following identification of their geo-references.(2)Descriptions of about 1,000 sites in the EcoNETVIS that Srisakra Vallibhotama surveyed were updated with regard to their geo-references and academic information. Walailak Songsiri engaged intensively in this work while in Japan.2.Improvement of the EcoNETVIS : ‘Site viewer' pages were introduced in the EcoNETVIS web page … More , http://pladaek.media.osaka-cu.ac.jp/econetvis/, which allow the user to superimpose aerial photographs and topographic maps of a site and to view academic information on the same page.3.Development of a system to support field surveys : A prototype field tool using a notebook PC and a GPS antenna has been developed. It supports navigation to sites and browsing of academic information and basic geographical images. Several field experiments proved the effectiveness in navigating easily and accurately to ancient sites, even these that have almost disappeared. Gradual improvements have been made and development will continue for future practical application.The developments described in 2 and 3 above are important methods by which our results can be applied in fields of the humanities where field surveys are essential. Providing methods by which local researchers and students can access basic academic materials is one way in which this project will enable preservation of intangible academic knowledge for the next generation.
