We had a huge earthquake in March 11th, 2011 called "the 2011 off the Pacific Coast of Tohoku Earthquake''. This caused many kinds of disasters and the wide-area damage all over the eastern of Japan. Against this catastrophe, we decided to establish the emergency mapping team and to realize the development of Common Operational Picture (COP) among the responders of ministries and agencies in the central government. There are, however, two big problems. First is that we had to collect and integrate many kinds and large volume of information, second is that it took much more time to figure out the actual damage. As the way to solve these problems, we selected "Mash Up Spatial lnformation''. In this activities, we realize the development of COP creating 500 maps in one and half month.
