EPT files can be queried to return a subset of the points that give you a representation of the area. As you zoom further in, you are requesting higher and higher densities. A dataset in EPT will contain a lot of files, however, the ept.json file describes all the rest.

Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. 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. The NOAA Office for Coastal Management (OCM) downloaded this data set from this AK DGGS site: https://elevation.alaska.gov/ These files were processed to make the data available for custom and bulk download from the NOAA Digital Coast Data Access Viewer (DAV) . The total number of files downloaded and processed was 1804. 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. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: The purpose of this data set is to provide LiDAR-derived topographic data for transportation planning and road construction. credit: AeroMetric The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

The files contained classified elevation and intensity measurements for the 2013 Coastal Plain project. The data were in AK State Plane Zone 4 NAD83 (2011), meters coordinates and NAVD88 (GEOID12A) elevations in meters. The data had the following classifications: 1 - Unclassified, 2 - Ground, 3- Low Vegetation, 6 - Buildings, 7 - Noise, 8 - Model Key Point, 9 - Water, 10 - Breakline Proximity. OCM processed all points to the Digital Coast Data Access Viewer (DAV). The metadata and the report said that there were Class 13 points (Bridges), but the OCM internal script to check the point classifications, resulted in 0 points with that classification. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Internal OCM scripts were run to check the number of points by classification and by flight ID and the gps and intensity ranges. 2. Internal OCM scripts were run on the laz files to convert from AK State Plane Zone 4 NAD83 (2011) meters coordinates to geographic coordinates, to convert from NAVD88 elevations to ellipsoid elevations using the GEOID12A model, to assign the geokeys, to sort the data by gps time and zip the data to database and to the AWS S3 bucket. dateTime: DateTime: 2022-11-14T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: Alaska Division of Geological and Geophysical Surveys (AK DGGS) date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: AK DGGS contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://elevation.alaska.gov/ protocol: WWW:LINK-1.0-http--link name: AK DGGS Elevation Portal description: Source Citation URL function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) publisher processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID12B) meters, using the GEOID12B grids provided by the National Geodetic Survey.
