Creation of a Geografical Image Data Base on Natural Disasters and Environment

建立了一个主要由数字、表格和图像组成的数据库，并附有关于近基地区自然灾害和环境的说明文本，如下所示。该数据库可通过CD-ROM或Internet介质使用。气象灾害与大气环境(PL-P47)：我们研究了以下情况下气象灾害的破坏状况，并收集了大气状况数据。这些数据由气象卫星图像、气象雷达数据、日本气象厅观测到的地面观测点气象数据等和我们自己的观测数据组成。(1)过去气象灾害造成严重破坏的案例主要发生在大阪府。例如：1961年的台风黛妮-莫罗托和山脚下的泥石流。1938年和1967年在神户的Rokko。(2)近两年来近海地区气象灾害的个例分析。例：9807号台风。(3)大阪府典型的大气现象。例：海陆风和热岛。(4)日本各季节的天气特征。例：气象卫星图像和天气图。地理图像(P48-P83)：(1)地貌图像：这些图像显示了Kinki地区的特征地形，并与新构造或海平面变化有关。(2)卫星图像：利用ADEOS AVNIR数据为大阪府各地区(8x6 KIN；“从卫星上看到我的小镇”)以及小范围区域准备彩色合成图像数据集。这些图像显示了近海地区地貌、土地利用、地貌灾害和植被的最新环境方面。(3)兵库县南部地震：教材《兵库县南部地震(大阪府教育中心，1996年)》介绍了地震和预防地震灾害的基本知识，建立了地震灾害数据库。

A data base composed mainly of figures, tables, and images with explanatory texts concerning natural disasters and environment in the Kinki area was built as follows. This data base can be utilized by the medium of CD-ROM or internet.1. Meteorological disasters and atmospheric environment (pl-p47) : We researched the state of damage of meteorological disasters in the cases mentioned below, and gathered data of atmospheric conditions. These data are composed of meteorological satellite images, meteorological radar data, the meteorological data at ground surface observation sites, and so on observed by Japan Meteorological Agency, and our own observation data. (1) Case studies of meteorological disasters caused serious damage mainly in Osaka prefecture in the past. Ex : Typhoon Daini-Muroto in 1961 and the debris flood at the foot of Mt. Rokko in Kobe in 1938 and 1967. (2) Case studies of meteorological disasters in the Kinki area for the last two years. Ex : Typhoon 9807. (3) Typical atmospheric phenomena in Osaka prefecture. Ex : A land and sea breeze and a heat island. (4) The features of weather at each season in Japan. Ex : Meteorological satellite images and weather maps.2. Geographical images (p48-p83) : (1) Geomorphological images : These images show characteristic topographies of the Kinki area and are related to neotectonics or sea-level changes. (2) Satellite images : Data set of color composite images was prepared using ADEOS AVNIR data for each local district ( 8X6 kin ; " View of our town from the satellite") of Osaka prefecture as well as small-scale regions. These images show recent environmental aspects of geomorphology, land utilization, geomorphic hazards, and vegetation of the Kinki area. (3) Hyogo-ken Nanbu earthquake : The textbook, Hyogo-ken Nanbu earthquake (Osaka prefectural education center, 1996), which gives a fundamental knowledge of earthquake and prevention of earthquake disasters, was made up into a data base of earthquake disasters.
