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

建立了以近畿地区自然灾害和环境相关的图形、表格、图像和说明文字为主要内容的数据库。该数据库可通过光盘或互联网等媒体进行利用.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危害状况，并收集了大气条件的数据。这些数据由日本气象厅观测的气象卫星图像、气象雷达数据、地面观测点的气象数据等以及我们自己的观测数据组成。(1)过去主要在大坂府造成严重损失的气象灾害案例研究。例如：1961年台风“大妮-室户”和山脚下的泥石流。1938年和1967年在科比的洛科。(2)近两年来近畿地区气象灾害的个案研究。例如：台风9807。(3)大坂府的典型大气现象。陆地和海洋的微风和热岛。(4)日本每个季节的天气特征。例：气象卫星图像和天气图。地理图像（p48-p83）：（1）地貌图像：这些图像显示了近畿地区的特征地形，并与新构造或海平面变化有关。(2)卫星图像：使用ADEOS AVNIR数据为大坂府的每个地方区（8X 6公里;“从卫星上看我们的城市”）以及小规模地区准备了彩色合成图像数据集。这些图像显示了近畿地区的地貌、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：介绍地震和地震灾害预防基本知识的教科书《兵库县南部地震》（大坂府教育中心，1996年）被制成地震灾害数据库。

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.
