Construction of a Web-Map to Present the Status of the Recovery from the Great East Japan Earthquake

Abstract

The Great East Japan Earthquake that occurred on March 11, 2011 brought serious damage in the Tohoku district in Japan. There have been many examples of utilization of satellite image analysis to grasp the situation of damage. However, henceforth, it is more important to monitor how the destructed environment will recover for a long time. From such a background, our research group is working on a project such as “A project on the recovery monitoring of the destructed environment in the disaster area by satellite data analysis and field work and the practice of earth environmental education.” The main purposes of the project are to monitor the status of the environment recovery from both aspects of satellite image analysis and fieldwork with high school students in the disaster area, and to practice earth environmental education for young people through such work. Moreover, to construct Web-based system to present the status of the environment recovery and the reconstruction of the disaster area clearly and to transmit this information all over the world are also purposes of the project. In this paper, we report on the implementation of a Web-based map to present the status of the recovery from the Great East Japan Earthquake by using both the data obtained by the fieldwork conducted by the project members and the National Land Numerical Information provided by the MLIT (Ministry of Land, Infrastructure, Transport and Tourism).
