[SVC30-P04] Construction and Provision of Digital Photographic Archives by Using the JVDN system
Keywords:Volcanic disaster, photo data, JVDN
Sharing visual information, e.g. photographs, is essential to deepen understanding of volcanic phenomena and to match perceptions of eruptive phenomena and volcanic disasters with those who were not there. Since volcanic eruptions are infrequent in many areas, there are few opportunities to directly witness volcanic eruptions and disasters. However, it is possible to visually share eruption phenomena and disasters through photographs. This is true not only between volcanic researchers, but also between volcanic researchers and non-experts.
The advantages of sharing photo data are as follows; Centralized photo data leads to efficient and rapid collection of multifaceted information. Sharing and archiving data can prevent data dissipation due to the retirement of the photographer and maintain a situation where the data can be utilized. Sharing photographic data can solve the problems of data aggregation and data storage that have existed so far.
Based on the above background, a function for photo sharing has been added to JVDN system for the purpose of effectively utilizing photo data. This allows JVDN system users to register and share their own photo data taken by individuals. It is possible to show the gradual copyright license conditions by the Creative Commons License. The fact that the photographer, shooting date and time, and location are required items for database input keeps the quality of the data above certain level. Then, the data sharing range can be selected, that is, the sharing range can be limited or completely disclosed, depending on the person to be shared. It is also possible to register using the arbitrary format file sharing function, so if you have a large number of photos, you can consider using this function.
As a first case, we uploaded a photograph related to the 1990-1995 eruption of Mt. Unzen to the JVDN system. We believe that this volcanic disaster case registered in the JVDN system can be used not only for volcanic disaster prevention education in the future, but also for verification of photographic data analysis methods for the events that have been clarified so far.
It is expected that photos which will be added in JVDN in future are able to be effectively utilized in various fields. We believe that sharing photographs of volcanic disasters will lead to strengthening cross-disciplinary collaboration among volcanic researchers, social scientists, and image analysis researchers etc.
