  "description": "These lidar data are processed classified LAS 1.4 files at USGS QL2 covering the District of Columbia. Some areas have limited data. The lidar dataset redaction was conducted under the guidance of the United States Secret Service. All data returns were removed from the dataset within the United States Secret Service redaction boundary except for classified ground points and classified water points.\n\nThis metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV).\n\nThe NOAA Office for Coastal Management (OCM) downloaded laz point data files from the Open Data DC site.\nThe data were processed to the NOAA Digital Coast Data Access Viewer (DAV) to make the data available for bulk and custom downloads. In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.\n\n",
