A two-phase algorithm for point-feature cartographic label placement

Multiple Geographical Feature Label Placement Based on Multiple Candidate Positions in Two Degrees of Freedom Space

“…Another common model for point feature labeling is the slider model, which can make better use of the blank area of the map through the continuous sliding strategy, but the position of the label is limited to this trajectory line. Recently, Ding et al [9] proposed an algorithm based on a four-slider model to place the label of point features.…”
