2017 Map of Koko Head OE E

About this map

Makapu'u Point anchors the western edge of this hydrographic-focused survey, marking the easternmost tip of Oahu as it meets the deep waters of the Kaiwi Channel. Most of the area is dominated by the Pacific Ocean, reflecting the coastal geography where Honolulu County’s maritime boundaries extend into the sea. The map documents the precise transition from the rocky headlands of the island to the open channel, a critical navigational passage between the islands. While primarily an oceanic sheet, it captures the high-water mark and the immediate coastal topography that has historically defined this prominent Hawaiian landmark.
