Implementation of Effective Field Survey for Damaged Buildings under Harmonious Collaboration between Human and ICT - A Case Study of 2018 Hokkaido Eastern Iburi Earthquake -

Based on the experience at past disasters, we have developed the effective method of inspection for each building damage. In this method, we developed only paper-based forms for damage inspection. However, with paper-based forms, we cannot control the quality of collected information, we cannot grab the progress of building damage inspection in real-time, and we cannot draw the whole picture of building damage in the affected area for rational and immediate decision making. Against these issues, we decided to develop an integrated system for effective and efficient building damage inspection utilizing mobile-GIS and cloud-based GIS. We designed the flow of Information Production dealing with information as a product, and developed an integrated system. In this process, we consider about how to realize harmonious collaboration between human and ICT. Finally, we implemented it at Abira town in Hokkaido, which was affected by 2018 Hokkaido Eastern Iburi Earthquake on 6th September. Through the on-site implementation for one month, we and local responders finished the damage inspection for all buildings placed in Abira town, which was over 7,200. Furthermore, we found that system supported their activity effectively, and we detected some issues we should solve for implementation at future disaster.
