Hawaii is a state in the United States at latitude 22°00′00.00″ North, longitude 165°00′00.00″ West.

Status

TIGER 2007 data were imported for all the main populated islands. These use NAD83 only for Oʻahu and use a different reference datum for all other islands. Lanaʻi, Molokaʻi, Maui and Big Island have been reimported from TIGER 2009 data, which use the NAD83 datum. Kauaʻi should be reimported from TIGER 2009 soon. Presently, mappers should refrain from mapping the islands that have not yet been reimported with NAD83-based data. These areas are easily recognized, because roadways are offset several hundred meters from satellite imagery and PGS coastline data.

State Routes

Hawaii/State Highway Relations is a page for tracking the progress of placing highways into relations within Hawaii.

Railroads

Due to recent wiki and associated software upgrades, the map details are not-quite-correct. To fix, please select "Transport Map" from the upper-right "layers stack" icon to see the railway routes. This is a "live" slippy map; it can be panned and zoomed.

While many states have a dedicated state-level Railroads wiki, Hawaii's fairly limited rail likely can be kept to this section. (Though, if you want to break this out to a dedicated Hawaii/Railroads wiki, go for it).

Hawaii's rail is exclusively passenger, there is no freight or military rail (known of to OSM) in the state. In 2019, prior to completion of Honolulu County High-Capacity Transit ("HART") Corridor Phase 1, Hawaii rail is otherwise largely usage=tourism, though there is passenger railway=monorail connecting some commercial/shopping areas. One tourism rail is on the island of Kaua'i, one tourism monorail is on Hawai'i and three railways (one monorail, one narrow_gauge and the HART light_rail) are on O'ahu.

It appears that not yet accounted for in the table below is a tourism-oriented passenger railroad on the western side of Maui, the "Sugar Cane Train" at Lahaina. Please enter into OSM route=railway and route=train relations and into the wiki table below.

Summarized in table form:

Railway/Line	Route	Train #	Relation	Status
'Ewa Plain Plantation Railroad	Narrow Gauge	Train #	9171965 9171965	Elements are tagged railway=narrow_gauge and usage=tourism. Contains some segments tagged railway=abandoned.
Skyline	Light Rail	Train #	15979957 15979957	Phase 1 of 2 / Western half (East Kapolei to Aloha Stadium) is open.
Honolulu County High-Capacity Transit Corridor	Light Rail	Train #	9172322 9172322	Phase 2 of 2 / Eastern half (Aloha Stadium to Ala Moana Center) is planned to open in 2025. Now, there is only underlying proposed infrastructure in the relation. At completion, please update this table after correcting tags, merge this relation into the one above.
Kauai Plantation Railway	Train	Train #	9171966 9171966	Elements are tagged usage=tourism at this sugar-cane plantation and rum-tasting center.
Pearlridge Center Monorail	Monorail	Train #	The single way is in OSM	The way, tagged railway=monorail, connects Pearlridge Center's separate Downtown and Uptown shopping areas.
Waikoloa Monorail	Monorail	Train #	9171972 9171972	Elements, tagged railway=monorail are also tagged usage=tourism. Serves Hilton Waikoloa Village on the Big Island of Hawai'i.

The colors chosen in the Route column are random; please change these to something more local/correct (and add a corresponding colour=* tag to the relation).

Issues

Many of the aboriginal Hawaiian names for geographic features and communities were repeated on several islands, because they were historically independent entities until the late 18th century. Since the US Postal Service requires city names to be unique, many cities were required to modify their names to disambiguate them. For instance, Kailua on the island of Hawaiʻi became Kailua-Kona, and Waimea on the island of Hawaiʻi became Kamuela. Although these disambiguated names are the official names required in mailing addresses, in practice the original name may continue to be used for most other day to day purposes. This is certainly the case for Waimea (Kamuela).

How should these cases be handled when labeling such places in OSM? I have seen instances of just the new name, just the old name, and dual labelling on various published maps.

Place Name Orthography

The Hawaiʻi Board on Geographic Names is an agency of the State of Hawaiʻi which is responsible for the official names and spelling for all geographic features within the state. It is the Board's current policy to include the ʻokina (glottal stop) and kahakō (macron) diacritic marks in official names, when there is solid evidence they should be part of the name. The Board primarily uses Place Names of Hawaiʻi (Pukui, Elbert & Mookini) and the recommendations of ʻAhahui ʻŌlelo Hawaiʻi, as well as the recollections of local Hawaiian speaking elders to make its determinations.

The WikiProject Hawaii Manual of Style on Wikipedia recommends using the diacritic marks in the body of articles when referring to Hawaiian place names.

The OpenStreetMap project should follow these precedents when adding name tags in Hawaiʻi.

Best practices

Put the name with ʻokina and kahakō in name=* and name:haw=*, and put the name without these in name:en=*. This will give renderers something to fall back on, and also guarantee search will work without specifying the diacritics.

If there is both a Hawaiian name and an English name (e.g., Coconut Island, also called Moku o Loʻe), you should either:

1. use both name=* and alt_name=*, with appropriate language variants; or
2. set name=Coconut Island (Moku o Loʻe), name:en=Coconut Island, and name:haw=Moku o Loʻe.

In either case, name:haw=* should only contain Hawaiian words and names.

Island coastlines

Islands should have their coastline tagged with place=island or place=islet. They should not have a node placed at their center for this purpose.

Since many of the large islands have the coastline broken into multiple segments, these segments should be placed in a multipolygon with outer role, and the multipolygon should then be tagged with place=island. The name of the island belongs on the multipolygon.

Any small islands, islets, rocks, etc., should be tagged by themselves if they have names. If no name is known, then consider them part of the bigger island they are near, and add them to that island's multipolygon.

To Do

This is a suggested list of outstanding items for the state of Hawaii. There may be many additional items to be done at a more detailed level that should be documented on the wiki page for each individual island.

• Complete the import of NAD83-based TIGER data for the neighbor islands. Big Island and Kauaʻi still remain to be completed
• Import bulk data from the Hawaii GIS department
  • Streams
  • Waterfalls
  • Coral Reefs
  • Dams
  • Ditches (for irrigation)
  • Islets - The PGS coastline data doesn't include all the tiny islets surround the main islands.
  • Mile Markers - Mile markers are commonly use for route descriptions.
  • Ne Ala Nele Trails - This may possibly overlap with some of the trail information already in OSM
  • Parks for Kauaʻi, Oʻahu, and Maui
  • Schools
  • Other layers may be of interest as well, including small boat ramps, pipelines and transmission lines, hotels (as of 2006), various administrative boundaries, landuse/landcover, etc. In the case of administrative boundaries, note that imported census boundaries should be tagged boundary=census rather than boundary=administrative and should not contain an admin_level=* tag.
