In Japan, most houses are made of wood. This results seismic fires as one of the biggest disaster among other damages. As for the city, it changes its structure every year, the enormous time and the expense are necessary to build and to maintain the fundamental data base which is necessary to draft a plan of the protection against disasters and so on. The purpose of this study is to develop the technique to estimate built-up area wooden percentage using the remote sensing data. Here, wooden building ratio is a coverage percentage by wooden buildings for every unit.The technique to estimate wooden percentage by this study is as follows. As for the wooden building, thermal capacity is small compared with the other kind of building structure. As the result, the pattern of the change of the surface temperature is different. This study aimed at this face and develop a method to estimate a wooden building ratio in urban. The satellite is doing observation with twice at 10 AM and 9 AM. Using … More these two sets of satellite date, the change pattern with surface temperature can be examined. In comparison between the thermal characteristics which can be seen from the two satellite data and the structural characteristics in the built-up area, the wooden building percentage will be obtained. It compared between the estimated result and the statistical value which made by a local government. By this comparison, the estimated precision was found as enough. When the green coverage percentage was large, the tendency which surface temperature change became smaller than when factual was obtained. Some example to be wooden and to mis-distinguish between the building and so on were seen in the subject area.The satellite data gave information with the texture which is smaller than with statistical value which gathered in the unit of street. In the investigation which used a statistical value, it overlooked up to this in the small critical section in the processing. It is expected that the discovery of the critical section becomes possible when using satellite data. Less

在日本，大多数房子都是用木头建造的。这导致地震火灾成为其他灾害中最大的灾害之一。对于城市来说，它的结构每年都会发生变化，需要花费大量的时间和费用来建设和维护基础数据库，这是制定防灾计划所必需的。本研究的目的是开发利用遥感数据估算建成区木材百分比的技术。这里，木质建筑覆盖率是指木质建筑对每个单元的覆盖率。本研究估算木质建筑覆盖率的方法如下。对于木结构建筑，与其他类型的建筑结构相比，热容量较小。因此，表面温度的变化规律是不同的。本研究针对这一现状，提出了一种估算城市木结构建筑比例的方法。卫星在上午10点和9点分两次进行观测使用…利用这两组卫星资料，可以考察地表温度的变化规律。将这两个卫星数据的热特性与建成区的结构特性进行比较，得到木结构建筑的百分比。并将估算结果与当地政府的统计值进行了比较。通过比较发现，估计的精度是足够的。当绿地覆盖率较大时，地表温度变化的趋势比实际情况小。以街道为单位收集的卫星数据所提供的纹理信息小于以街道为单位收集的统计值。在使用统计值的调查中，在处理过程中的小关键部分忽略了这一点。预计在使用卫星数据时，发现关键部分成为可能。较少
