Japanese non-profit organization (NPO) Crisis Mappers Japan has started a crowdfunding campaign on Japan’s crowdfunding website ReadyFor for a project called Drone Bird, which aims to reflect the damaged states after disasters to maps rapidly and accurately utilizing drones. Crisis Mappers Japan has been engaged in activities of mapping the damaged state onOpenStreetMap based on satellite photographs when natural disasters occur, for the purpose of making use as lifesaving or supporting activities. Previously, the first problem of its method was that it takes more than two days to complete mapping although immediacy of information is strongly required upon disasters. Therefore, the team started to form the plan of Drone Bird, which is to arrange state-of-the-art drones and their operators in ten places around Japan in order to collect image data of the damaged state rapidly.
