© 2018 IEEE. We study the problem of continuous maintenance of range sum heat maps over dynamically updating data objects. The range sum (RS) here refers to the sum of the weights of the data objects enclosed by a given range (rectangle) R. Range sum problems are useful in spatio-Temporal data analytics and decision making processes. Recent studies on range sum problems focus on computing the MaxRS query, which finds a location to place a rectangle R such that its RS is maximized. In real applications, knowing only the location with the maximum RS may be insufficient, because decision making is a multi-factor process where maximizing the RS may just be one of the factors. It is also importan..View full abstract
