Many space agencies in the world nowadays provide their emergency observation data to the public free of charge in the event of a large-scale disaster. International Disaster Charter is a framework to accomplish it in the international scale. And, Sentinel Asia is a regional one for Asia-Pacific, but it involves not only space agencies but disaster management organizations, research institutes and universities in the region. It means that Sentinel Asia functions not only to deliver the data to the users but also to produce value-added products(VAPs) and disseminate them to the relevant organizations. The University of Tokyo and Asian Institute of Technology have been responsible for the data analysis and the capacity building program in Sentinel Asia for more than 10 years. In the last three years, 96 cases of disaster were responded by Sentinel Asia, and VAPs were produced in most cases. Based on this experience, technical issues for VAP to be effectively used in emergency disaster response are discussed, referring examples of standard VAP for several types of disasters such as floods, earthquakes, landslides, etc. Moreover, our future efforts to improve the accuracy and reliability of VAP are introduced.
