64674 2010 FFS m9303 Data Set Published / External 37231 Lidar Project Completed 2014-04-17 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 French Frigate Shoals. This dataset contains lidar point clouds in LAS 1.2 format, classified according to the ASPRS LAS 1.2 class table. 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. Original contact information: Contact Name: Lidar Manager Contact Org: Aerial Surveying Inc.

Need to get it added. Cloud Cover: 0 Complete Data has been verified using ground survey points collected by the National Oceanic and Atmospheric Administration lidar data 1 Data were received 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. 2014-04-17T00:00:00 Organization Office for Coastal Management OCM https://ror.org/05v14bq57 2234 South Hobson Avenue Charleston SC 29405-2413 https://www.coast.noaa.gov/ lidar data 2 LAS files for French Frigate Shoals could not be located. ASCII text versions of the point clouds did exist with x, y, z, intensity, class, return number, and GPS seconds of the week. For Tern island, the ITRF00 ellipsoid heights text file existed. For the smaller islands, only the ITRF00 EGM96 orthometric heights text file existed. The smaller islands were converted to ellipsoid heights by reversing EGM96. All data was converted from UTM zone 3 to geographic coordinates. The data was converted from ASCII to LAZ format with LAStools txt2las. The GPS seconds of the week were converted to adjusted GPS time using LAStools las2las -week_to_adjusted 1593. 2021-05-20T00:00:00 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource lidar data gov.noaa.nmfs.inport:64674 Kirk Waters 2021-05-20T13:59:11 SysAdmin InPortAdmin 2026-03-04T19:17:17 2022-03-16 Office for Coastal Management OCM 1002 Public No No 2022-03-16 1 Year 2023-03-16
