The U.S. Geological Survey (USGS) contracted with Hawaii-based Aerial Surveying, Inc. to collect lidar-derived elevation data over the low-lying areas within the northwestern Hawaiian Islands (NWHI) during the summer of 2010. A separate contract issued to Aerial Surveying, Inc. by the National Oceanic and Atmospheric Administration (NOAA) funded the lidar data processing and elevation data product development phases of the project. Lidar data provide high resolution digital elevation models that are used for many applications, including but not limited to sea level rise modeling, habitat assessments, and tsunami inundation modeling. In April 2011, NOAA Papahanaumokuakea Marine National Monument and NOAA Office for Coastal Management deployed a survey crew to the NWHI to collect high accuracy point data to validate the 2010 lidar data. The survey crew used survey-grade Global Positioning System (GPS) receivers to collect high accuracy elevation points.
This metadata covers the information for Midway Atoll.
This dataset contains lidar point clouds in LAS 1.2 format, classified in the following ASPRS standards as Class 1: Unclassified, Class 2: Ground, and Class 9: Water.
The following are the equipment used to create the lidar data sets.
Aircraft: Beechcraft Queen Air
Lidar Systems: Riegl 140 and 240
Accuracy statements are based on areas of open terrain, with points classified as ground. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas.
Classified data sets such as this one may have varying posting due to some pulses not reaching the ground.
This work was conducted under permit number PMNM-2010-033 as approved by NOAA, the U.S. Fish and Wildlife Service (USFWS), and the State of Hawaii, and acknowledged by Dr. Charles L. Littnan of NOAA's Pacific Islands Fisheries Science Center.

Conceptual Consistency
Data has been verified using ground survey points collected by the National Oceanic and Atmospheric Administration
Data were recieved by NOAA Office for Coastal Management (OCM) and NOAA Papahanaumokuakea Marine National Monument (PNMN) from Aerial Surveying Inc. and tested for accuracy nine months after lidar collection. Full metadata was not received. Data were not originally classified for ground points and a separate contract had been done to classify the points. When OCM reviewed the classified data in 2014, the LAS files were found to be corrupt. OCM reclassified the original data using the MARS software package for ground and water points.

The vertical values in this data set have been converted to reference the Earth Gravitational Model of 2008 using the 1 minute grid transforms from https://earth-info.nga.mil/GandG/wgs84/gravitymod/egm2008/.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
