Middle Rocks and South Ledge are two maritime features to the south of Pulau Batu Puteh (Pedra Branca). Middle Rocks consists of two clusters of rocks situated 0.6 nautical miles south of Pedra Branca. The disputed South Ledge is to be a no-man land. South Ledge is a low-tide elevation (in other words, it is submerged at high tide) further south, 2.1 nautical miles, of Pulau Batu Puteh. In 1979, Malaysia published a map which showed for the first time that Pulau Batu Puteh lay within its territorial waters. This judgement concludes the 28-year dispute with Singapore.
