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：目前，我们的项目正在进行基础数据的收集和数字化。平条都城发掘图、平条都城数字高程模型、平条都城排水数据。平条都城发掘图：平条调查图是缩小比例1/2000。挖掘区域的位置和发现的古街被输入到地图中。数字数据用于此发布。平条首都数字高程模型（DEM）：根据1/2000的地图制作平条DEM。这张地图是用扫描仪读入的，并在解压缩后转换成矢量数据。我们相信这些数据的收集和积累不仅对考古学的研究是有用的，而且对许多其他领域的研究和应用也是有用的。我们的研究成果将以书籍和数据汇编的形式出版。平条资本流失数据：现在，我们从研究机构的挖掘中收集了262条排水沟的基本数据记录，为了分析整个平条京市的水系，我们将收集两岸的上下边缘和排水沟的最深点的数据，并在给定的时间间隔内提取。对土地层横截面的某些区域的观测提供了重要的信息，这些信息提供了有关排水沟变化的线索，因为它揭示了沟的掩埋和重塑。纳入这类资料是高度优先事项。

The collection of the basis data : At present, 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 Elevation Model, the Heijo capital drain data.Heijo capital excavation map : The Heijo investigation map is the reduced scale of 1/2000. The position of the excavation area and the found ancient street is inputted to the map. A digital data is used for this publishing. We are planning to use for the GIS that utilized the data.Heijo capital Digital Elevation Model (DEM) : We create the Heijo DEM from the map of 1/2000. This map is read in using a scanner, and converted into vector data after skeletonization. It is finally converted into mesh data.We believe that such data that has been collected and accumulated is useful not only in archaeological research but also in research and applications in various many other areas. The results of our research will be published in the form of books and data compilations. Heijo capital drain data : Now, we collected 262 records of basic data at drainage ditches from an excavation conducted by research institute.In order to analyze the entire water system in the Heijo Kyo city, data will be collected regarding the top and bottom edges of both banks and the deepest points of the drainage ditches extracted at given intervals. Observation of some areas of the cross-section of the land layer provide important information that provides clues regarding changes to the drainage ditches because it sheds some light on the burying and remodeling of the ditches. The incorporation of such information is given high priority.
