Database for weather radar and image processing system

Abstract

Most of radar hydrogists in Japan have spent a lot of money and time to read and arrange many magnetic tapes recorded by weather radar. A standard format is proposed to share the data file observed by weather radar. We suggest a RAF1 and a RAF2 radar data formats for sequential and random access files. Two systems for the standard file format are also introduced.One is a database system using the RAF2 file format. The other is an image processing system which could treat the data from the database system as image pixels to trace the movements of the rainfall areas.
