Range Nearest Neighbor Query with the Direction Constrainty). Traditional DCNN query retrieves the top-. nearest neighbors within an angular range. Our Range-DCNN query finds all nearest neighbors within an angular range for all points in a rectangle. Dissimilar to the traditional DCNN query, the user’s location in the Range-DCNN query is abstracted to a r
