Applying remote sensing and spacial analysis technology to locating transitional shelters in earthquake areas

Violent earthquakes damaged buildings, towns and cities. The earthquakes and the subsequent secondary disasters, such as landslips, landslides and debris flows, brought immediate threats to people there. The rescue tasks need updated and appropriate information for site selection of emergency refuges and transitional shelters, especially when a city has been destroyed and the original earthquake emergency refuge planning can no longer work well. This paper introduced remote sensing and spatial analysis technology to locating medium and long term transitional shelters in Wenchuan earthquake areas. The proposed model assessed geological security, rescue path, service range, water system, land coverage and topographical factors, and acquired a valid result.
