DEVELOPMENT OF SATELLITE IMAGE DATABASE SUPPORT SYSTEM FOR ESTIMATION OF METEOROLOGICAL DISASTER POTENTIAL

将东北大学NOAA卫星的HRPT/AVHRR数据编辑成图像数据库JAIDAS，供公众用户进行时间序列分析，为使用个人计算机的用户开发了图像数据库JAIDAS的支持系统。开发的系统通过免费软服务器向公众用户提供服务。该系统包括以下内容：1.JAIDAS图像查看器：该程序可以显示CH-2和CH-4两个通道的图像，以及亮度/亮度-温度直方图。用户可以选择范围图像、全尺寸(1024x1024)或部分区域(300x300或100x100)和任意灰度级的显示。2.分类方案：基于图像的二维直方图，可以在PC显示器上进行类别分类。3.图像匹配：支持与经纬度系统的细节图像匹配。4.时序图像的相关分析实用程序5.LISPS-3型打印机的打印实用程序。

NOAA-satellite HRPT/AVHRR data recieved at Tohoku University are compiled as the image database JAIDAS and served to public user for time series analyzes.In this study, a support sysytem of the image-database JAIDAS have been developed for users who utilize personal computers. The developed system is served to public user through free-soft-server. The system contains follows :1.A viewer of JAIDAS image : This program can show two channel images, Ch-2 and Ch-4, together with histogram of brightness/brightness-temperature. User can select the range image, full-size(1024x1024) or part areas(300x300 or 100x100) and arbitrary gray scale of display.2.Classification program : Basing 2-dimensional histogram of image, a category classification can be carried out on PC display.3.Image matching : Detail image matching to the latitude-longitude system is available.4.Correlation analysis utility for time sequential images5.Print out utility for LISPS-3 type printer.
