Moving regions play an important role in our day to day lives, for example, hurricanes, rain clouds, etc., change shape and position over time. There is a lack of research on indexing moving regions. In this paper, we create a new index structure to support querying moving regions. The proposed model (Q+ IB+ tree) uses a combination of the quadtree and an interval B+ tree. The model uses the top view of the moving regions in the quadtree and approximates the movement using the Minimum Bounding Rectangle (MBR) between each of the region's time intervals (IB+ tree). Also, we evaluate spatio-temporal queries with this model to check its feasibility and compare it to other indexing techniques.
