Diagnostics of Soundness of Agricultural Facilities and Development of Environmental Assessment Using GIS

1. GIS系统的构建作为GIS系统，介绍了ESRI公司的ArcInfo。该系统具有地形图、空间图显示、地理信息检索、三维地理数据分析、编辑和管理等功能。这些功能以软件的形式实现，并与合适的PC服务器系统配合使用。2003年，我们接受了掌握系统操作的培训。以福岛县郡郡山市西田町2km × 2.5km的矩形区域为例，利用卫星图像数据进行GIS分析。该数据包含绝对平面坐标和2.5m网格点的数字高程数据。将GIS的高程数据与实测的精密地理高程数据进行比较，可以看出前者具有相当高的精度。此外，通过引入Voxcel的概念，使用基本GIS网格和由基本网格衍生的5 m和10 m网格对模拟地形进行了重建。之间的关系 关于我们 2.利用红外热像仪和声发射技术检测混凝土结构的裂缝尝试了利用红外热像仪检测任意远距离混凝土结构表面的裂缝，并与此相结合，提出了一种基于红外热像仪和声发射技术的混凝土结构裂缝检测方法。3.暴雨条件下边坡破坏原因的判断2.对1km左右的试验分析区进行了试验分析在长野县和新泻县边界附近的姬川流域选择了2个。调查的目的是确定暴雨引起的边坡破坏的原因。选取植被指数、坡度、坡向、地表地质和地下水位下降面（本研究首次提出这一概念）5项作为物理性质特征。这5个因素被作为数量化理论II中的“项目”。4.宽范围电磁波剖面仪地质调查技术的发展5. 2004年第23号台风暴雨袭击引起的阿和治岛灌溉池塘破坏分析的GIS应用

1.Construction of GIS systemAs a GIS system, "ArcInfo" made in ESRI Co. was introduced. This system is able to display topographical map, space map, retrieve geographical information, analyze, edit and manage 3-dimensional geographical data. Those functions are delivered by the form of software and works with suitable PC sever system. In 2003, we trained to master the manipulation of the system. As a case study, the satellite pictorial data of 2km by 2.5km rectangle area in Nishida town, Ko-oriyama city, Fukusima prefecture were used and GIS analysis was carried out. This data contains absolute plane coordinate and digital elevation data with 2.5m mesh point. Comparing the elevation data of GIS and measured precise geographical one, it became clear that the former has a considerable high precision. Moreover, by introducing Voxcel concept, reconstruction of the simulated topography using basic GIS mesh and 5m and 10m mesh derived from basic mesh was examined. The relationship between th … More e size of Voxel and mesh size was clarified, and the useful results were obtained.2.The detection of crack on concrete structures using thermograph and AE measurementThe detection of crack on any concrete structure surface of long distance using the infrared photograph was tried, and together with this, AE measurement of cracked structure was also tired.3.Estimation of cause of slope failure by heavy rain2 test analysis area of which size is around 1km^2 were chosen in Hime-river basin expanded around border of Nagano and Niigata prefecture. The investigation was aimed to define cause of slope failure caused by heavy rain. As characteristics of physical properties, following 5 items were chosen, i.e. vegetation index, slope inclination, slope direction, surface geology and falling water table surface(this concept was first defined in this research). These 5 factors were used as "items" in the theory of quantification type II. The results showed the degree of affection to the failure of each items.4.Development of geological survey technique using wide range Electro Magnetic wave profiler5.GIS application of failure analysis of irrigation pond in AWAJI Island caused by the heavy rain attack of Typhoon No.23 on 2004 Less
