Current Status and Future Directions of Open Access to Photogrammetric Data Surveyed During Disasters : A Case Study of the Geospatial Information Center

In recent years, Japan has experienced an increasing number of severe natural disasters, highlighting the need for rapid acquisition and dissemination of disaster-related information. The photogrammetry industry plays a critical role by providing various types of data, including oblique imagery, orthophotos, airborne LiDAR data, and microtopographic visualization maps. These datasets are essential for understanding damage conditions and supporting recovery planning. However, despite their importance, secondary use of such data remains limited due to licensing restrictions and challenges in data distribution.
