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.

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).

Please read ‘Description-Map of Offshore Bathymetric Transects along Peak Wave Directions.docx’ for detailed information.

[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.

As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterizing stratigraphy near Oahu, Hawaii (HI) May 7-13, 2023. The purpose of this study was to conduct a geologic assessment (including bathymetric mapping) near Fort Hase Beach, Oahu, in support of efforts to construct an artificial coral reef offshore of Marine Corps Base Hawaii (MCBH). This publication serves as an archive of high-resolution chirp subbottom trace data, survey trackline map, navigation files, geographic information system (GIS) data, and formal Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Processed subbottom profile images are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG-Y revision 1 format (Norris and others, 2002). In addition to this data release, the SEG-Y files can be downloaded from the USGS Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov.
