"Ouranos 4D Spatio-temporal ID" (abbreviated as Spatio-temporal ID) serves as an index for easily integrating, retrieving, and freely distributing a wide variety of spatial information (including temporal information). "Spatio-temporal ID" is a combination of "Spatial ID," which is an identifier in three-dimensional space, and "Temporal ID," which is an identifier in the time axis.
