To tackle these growing challenges, Shizuoka

form of social infrastructure and is making it opensource. It aims to enhance productivity and generate
new value by constructing Virtual Shizuoka, a virtual

The efforts of Virtual Shizuoka have inspired theTokyo Metropolitan Government to advocate for theacquisition of point cloud data and the release ofopen source data, and other localities have followed
suit with similar initiatives.
