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

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

Hawaii/State Highway Relations is a page for tracking the progress of placing highways into relations within Hawaii.
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) in the state. In 2019, prior to completion of Honolulu County High-Capacity Transit Corridor Phase 1 (to be known as "HART"), Hawaii rail is 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 emerging HART light_rail) are on O'ahu. Summarized in table form:
|'Ewa Plain Plantation Railroad||Narrow Gauge||Train #||Elements are tagged railway=narrow_gauge and usage=tourism. Contains some segments tagged railway=abandoned.|
|Honolulu County High-Capacity Transit Corridor||Light Rail||Train #||Phase 1 of 2 / Western half (East Kapolei to Aloha Stadium) now under construction, underlying infrastructure in the relation. At completion, please update this table after removing construction tags. Revenue service expected late 2020.|
|Honolulu County High-Capacity Transit Corridor||Light Rail||Train #||Phase 2 of 2 / Eastern half (Aloha Stadium to Ala Moana Center) is planned, not funded, underlying proposed infrastructure in the relation. At completion, please update this table after correcting tags, merge this relation into the one above. Revenue service estimated late 2025.|
|Kauai Plantation Railway||Train||Train #||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 #||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).
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.
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:
- use both name=* and alt_name=*, with appropriate language variants; or
- 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.
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.
- The Hawaiʻi State GIS Program has an extensive list of GIS data that is in the public domain that could be utilized by the OSM project.
- See also Potential_Datasources#Hawaii
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
- Coral Reefs
- 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
- 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.
