A GIS Application for the study on water supply and draining system in the ancient capital city in Japan.

基础数据的收集：我们的项目正在进行基础数据的收集和数字化。它是平初都城开挖图、平初都城数字高程模型、平初都城排水数据。对于制作基础数据，需要转换图表1宽度的成本是非常高的。可以说，能够探索出快速、低成本地实现这些基础数据生成的方法是一个重要的成果。将排水数据安装在GIS上，并对与平洲桥大部分流域有关的调查点进行显示和比较研究成为可能。从研究之初就考虑到这些成果，有必要对近年来空间信息处理设备的发展和空间信息处理技术的发展加以重视。认为通过开挖调查，将三维沟的形态布置并向公众开放，是对今后研究有益的成果。

The collection of the basis data : Our project is proceeding with the collection and the digitization of the basis data. It is a Heijo capital excavation map, the Heijo capital Digital Elevarion Model, the Heijo capital draining data.As for making the basic data, the cost that requires it to convert the width of chart 1 is very high. It can be said that being possible to grope for the method of achieving the generation of these basic data promptly and at a low price is an important result.Mounting the drain data on GIS, and displaying, and making comparative study of the investigation point that related to most Jou in Heijokyo became possible.It is necessary to develop the equipment in recent years and the development of the spacial information processing technology while remarkably taking these results in the future when thinking from beginning the research.It thinks the arrangement, and opening to the public the shape of the ditch of three dimensions by the excavation investigation to be a result profitable to research in the future.
