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

这是一个第二阶段项目，延续了2000至2002财政年度题为“通过时间序列空间信息系统的过去和现在：泰国东北部定居点的连续性和间断性”的前一个项目。主要活动和结果如下：1.聚落连续性和间断性数据库(1)将大约350张20世纪50年代的地形图和大约100张80年代的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。大约800张20世纪50年代的航拍照片在确定地理参照后仍在逐步存档。(2)Srisakra Vallibhotama调查的生态网中约1,000个地点的描述更新了地理参照和学术信息。在日本期间，Walailak Songsiri深入参与了这项工作。2.EcoNETVIS的改进：在EcoNETVIS网页…中引入了“站点查看器”页面3.开发支持野外测量的系统：开发了一个使用笔记本电脑和http://pladaek.media.osaka-cu.ac.jp/econetvis/，天线的原型野外工具。它支持网站导航以及学术信息和基本地理图像的浏览。几个现场实验证明，该系统在轻松、准确地导航到古迹方面是有效的，即使是那些几乎消失的古迹。现已逐步改进，并将继续发展，以便今后的实际应用。上文第2和第3段所述的发展是将我们的成果应用于需要实地调查的人文领域的重要方法。为当地研究人员和学生提供获取基本学术材料的方法是该项目为下一代保存无形学术知识的一种方式。较少

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.
