The purpose of the 2007 Hawaii survey, in general, was to collect both bathymetric and topographic lidar along the northern coastline of the Hawaiian Islands. Topographic data were required between the zero and 15 meter contours, nominal, for the northern coastline of the islands of Hawaii (Big Island), Kauai, Maui, Molokai, and Oahu. Bathymetric Lidar data collection was attempted in Kaneohe Bay, Oahu, to fill-in the data gaps between the shoreline and the previously collected SHOALS data. Bathymetric Lidar data were collected on the island of Hawaii from Honolii Stream south along the shoreline to the existing SHOALS data. The data were to be collected from the land water interface seaward to a depth of 40 meters or laser extinction, whichever comes first. These data were collected for Hawaii State Civil Defense for tsunami mapping purposes. The manager for this project was Milton Yoshimoto (808) 438-2250.

These data are not attributed.
The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75 m.
The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20 m.
These data covered the required survey area with minimal gaps in data coverage except near tops of mountains. These gaps are caused when the ground elevation rises so high that the lidar swath (based on maximum scan angles and altitude) from adjacent flight lines no longer overlap. These gaps are at elevations above that maximum required for this project. The data postings are very consistent with postings nominally at 1.3 m density.
The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters, and different flight line data agreed within 0.20 meters.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.
