Abstract
This research focuses on a network based data distribution and visualization system of Multi-functional Tranport SATellite (MTSAT) . Institute of Industrial Science (IIS) and Institute of Earthquake Research Institute (ERI) both at University of Tokyo have been receiving, processing, archiving and dis-tributing of MTSAT imagery with a direct receiving of High Rate Information Transmit (HRIT) since October 2006. A software package, mtsatgeo, is developed including radiometric calibration, geometric cor-rection and spatial subset, and they are available on a web-based data distribution and processing service accessed at http: //webgms.iis.u-tokyo.ac.jp/
