Definition
Consider a number of objects moving continuously on a 2‐dimensional universe over some time interval. Given the complete archive of the spatio‐temporal evolution of these objects, we would like to build appropriate index structures for answering range and nearest neighbor queries efficiently. For example: “Find all objects that appeared inside area S during time-interval \( [t_1, t_2) \)
