Archaeological Research of the centhalKibiregion with the aid of spatial information sciences

1.完成了冈山市筑栗山古坟的钥匙孔状冢的调查。这座土丘是日本第四大土丘。采用两种测量方法：传统的平表法制作等值线图和利用GPS和全站仪进行数字化测量.新的测量方法使土墩的地图空前精确，结果我们可以很容易地区分土墩的原始部分和修改部分。然而，我们无法确定护城河的存在。因此，未来的挖掘工作是必要的。利用全球定位系统和全站仪测量墓土丘的新方法得到了广泛的检验。研究并初步建立了利用地理信息系统对结果进行分析和可视化的技术流程.收集了航空照片、卫星照片、旧地图和发掘成果等空间信息科学的综合研究数据。对筑栗山古坟石棺进行了三维激光测量试验.尝试了雷达探测和电子探测来识别墓室和护城河。在新绘制的等高线图的基础上，复原了筑栗山古坟的建筑平面图，并讨论了其他坟土丘的确切年代.研究报告发表了：2008年冈山筑栗山古坟调查的中期报告。

1. Accomplished the survey of a keyhole-shaped burial mound, Tsukuriyama Kofun, Okayama City. The mound is the fourth largest one in Japan. Two methods of survey were adopted: the traditional plain-table method for making contour maps and the digital survey using GPS and total stations.2. The new method of the survey brought about unprecedentedly exact maps of the mound In the result we can easily distinguish original parts of the mound and modified ones. However we could not identify the presence of moat. For this reason future excavations are necessary.3. The new method of surveying burial mounds using GPS and total stations were widely examined. The technical process of analyzing and visualizing the results using GIS were also examined and almost established.4. Comprehensive data for the research using spatial information science such as aerial photographs, satellite photographs, old maps and excavation results were collected.5. The three-dimensional laser survey of the stone coffin of Tsukuriyama Kofun was tried.6. Radar detections and electric detections to identify the burial chamber and the moat were tried.7. On the bases of newly depicted contour map the construction plan of Tsukuriyama Kofun was restored and the exact chronology within other burial mounds was discussed.8. The report of the research was published: The Interim Report of the Survey of Tsukuriyama Kofun, Okayama City in 2008.
