Kohala, Hāmākua and Hilo, Island of Hawaiʻi: the U.S. Geological Survey’s 1:62,500 quadrangles Kohala (1913), Waipio (1916), Hamakua…
The Geological Survey’s first topographic maps of the windward and northern coasts of Hawaiʻi Island, joined into one sheet: the trails into the valleys of Waipiʻo, Waimanu and Pololū and along the Kohala and Hāmākua coasts, with the land divisions and Hawaiian place names of the 1910s.

| Rights | Public domain. Published 1917 — before 1931, so public domain in the United States. Evidence |
| Accuracy | About 3 km. Placed by hand in a map-queue session and approved by a person. If something sits in the wrong place, members can fix it with Fix placement on the map. |
| Method | Joined from five georeferenced USGS GeoTIFFs: each quadrangle reprojected to longitude and latitude and cut at its neatline (the Kohala sheet up to 20°17′, where it draws the island’s tip above its neatline), then placed with the 67 corners of its 5′ grid (an exact fit). The sheets were drawn on the Old Hawaiian datum, so positions can differ from today’s by a few hundred metres. See the methodology. |
