[Metadata] Description: TMK Parcels for the State of Hawaii - 2025; specific dates vary by county. Sources: County of Hawaii: 5/16/25; County of Maui: 5/30/25; City and County of Honolulu: 6/3/25; County of Kauai: 6/2/25. Hawaii Statewide GIS Program projected to a common projection/datum (UTM Zone 4, NAD 83 HARN) and merged all counties' parcel data into one layer. Where necessary, the State standardized field names or added fields to the county layers such as creating text fields for corresponding numeric tmk fields, etc., and / or calculated values for fields such as links to qpublic.com websites showing additional information for each parcel. The parcel boundaries are intended to provide a visual reference only and do not represent legal or survey level accuracy. Attributes are for assessment purposes only and are subject to change at any time. For more information, please refer to metadata at https://files.hawaii.gov/dbedt/op/gis/data/tmk_state.pdf or contact Hawaii Statewide GIS Program, Office of Planning and Sustainable Development, State of Hawaii; PO Box 2359, Honolulu, Hi. 96804; (808) 587-2846; email: gis@hawaii.gov; Website:https://planning.hawaii.gov/gis.

Map NavigationClick on the blue points to find out more information about the public shoreline/beach access location. The pop-up will give you the access point name, type of access surface, and facilities available. Click here for a downloadable PDF of the Public Shoreline/Beach Access Locations Map.To view metadata or download this data, visit the State's Geospatial Data Portal. Comprehensive shoreline access information was gathered from field surveys and cross-referenced with City & County of Honolulu tax map key data.The information provided in this map should only be used as a general reference. It provides the public with an approximate account of the publicly accessible shoreline access points, which are either owned or leased by the City and County, the State or the US Government and are intended to be used for the public to access the shoreline, but does not include all possible points of entry to the coastline.Explore more interactive maps at the City & County of Honolulu's Maps of Oahu website.

Government land ownership in the State of Hawaii: Federal, State, State Department of Hawaiian Home Lands (DHHL), and County. Source: City and County (C&C) of Honolulu (July 2013), Kauai County (January 2012), Maui County (July 2013), Hawaii County (June 2013). This dataset was created using the Large Landowners layer that was derived from the Tax Map Key (TMK) Parcel shapefiles from the counties of Honolulu, Kauai, Maui and Hawaii. Lands were selected for Type = "Public".

[Metadata] Description: TMK Plats for the State of Hawaii. Created May, 2018. Sources: City and County of Honolulu: 4/20/18; County of Maui: 4/24/18; County of Hawaii: 5/1/18; County of Kauai: 5/4/18.

This database consists of a series of maps and plots showing elevations of offshore bathymetric transects perpendicular to State of Hawaii Department of Transportation (HDOT) routes in the Hawaiian Islands. Individual maps show transects of coastal areas adjacent to 302 mileposts along State of Hawaii Department of Transportation (HDOT) state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report.

Mileposts are identified by Brandes et al. (2019). HDOT state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Elevations along the transect are referenced to local mean sea level (LMSL) and are sampled from a Hawaiian bathymetric digital elevation model (DEM) created by the Hawaii Mapping Research Group (HMRG, 2016).

This Data set is - Tax Parcels (TMK) There are there are three parcel types; 1) tax and regulatory, 2) tax, and 3) regulatory. Type 1 are a combination of both Tax and Regulatory Parcels.Type 2 are Tax Parcels (TMK) which reflects divisions of property for the purpose of assessment by Real Property.Type 3 are Regulatory depiction of parcels reflects the division of property according to permitted applications for subdivision and consolidation as processed by DPP.

[Metadata] Description: Detailed Government Landownership in the State of Hawaii as of 2022: County, Federal, State, and State DHHL Lands (by TMK parcel) Sources: County of Kauai, April, 2022; City & County of Honolulu, April 27, 2022; County of Maui, April, 2022; County of Hawaii, April, 2022; State Department of Hawaiian Home Lands, October, 2022. This dataset was created using ownership information provided by the counties via tax map key parcel layers and ownership tables. Parcels were queried using the "Owner" field for state, county, and federal agency names. State GIS staff verified land ownership using the online service QPublic, the 2022 Department of Hawaiian Home Lands layer and other GIS layers and resources. Where ownership was still unclear, State GIS personnel reached out to appropriate agencies for clarification. Standardization and Summary fields "ownedby," “majorowner” and “type” were created using additional filters and queries. The parcel boundaries are intended to provide a visual reference only and do not represent legal or survey level accuracy.

This database consists of a series of maps showing estimated inundation by sea-level rise (SLR) of +1, 2, and 3 feet on Hawaiian Islands. Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report.

Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Shoreline datasets are provided by NGS (2017). Future SLR for +1 ft, +2 ft, and +3 ft are shown with respect to mean higher high water (MHHW).
