The QL2 requires collection of 2 points per square meter (ppsm), nominal LiDAR pulse spacing of no greater than 0.7 meter for 463 square miles and 4 PPSM for 494 sq. miles and a vertical accuracy of better than 10-cm RMSE. (Merrick will provide data to a 9.25cm vertical accuracy in the interest of meeting a 1 foot contour accuracy specification and this will still meet the QL2 specification). The NOAA Office for Coastal Management (OCM) downloaded this lidar data from the USGS ftp site, processed it and made it available on the NOAA Digital Coast. In addition to this lidar point data, bare earth digital elevation model (DEM) raster and breakline data are also available. Links to these data are located in the URL section of this metadata record. The breakline data has not been reviewed by the OCM and is made available at the user's discretion . This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: 957 square miles of 2 ppsm and 4 ppsm LiDAR to USGS QL2 specifications to support the Municipality base mapping efforts. credit: Municipality of Anchorage, AK; Merrick & Co; McElhanney The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

The raw data was verified in MARS software for complete coverage of the project area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: unclassified points, ground points, low points, water, ignored ground, Bridge Decks and Culverts. The data was next taken into MARS to reclassify the erroneous points that may remain in the LIDAR point cloud after auto filter. dateTime: DateTime: 2016-11-29T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) downloaded the data in laz format from the USGS site on Nov 2, 2017 (ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/NED/LPC/projects/USGS_LPC_AK_Anchorage_2015_LAS_2017/) . The files contained lidar elevation and intensity measurements. The data were in UTM Zone 6 (NAD83) meters coordinates and NAVD88 (Geoid12a) elevations in meters. OCM did the following processing to the data for Digital Coast storage and provisioning purposes: 1. File names were changed to remove USGS_LPC_2017 and _LAS_2017 from the filenames. 2. Converted from UTM Zone 6 (NAD83) meters coordinates to geographic coordinates 3. Converted from NAVD88 elevations to NAD83(2011) ellipsoid elevations using Geoid12a grids 4.
