The data is organized in such a way that the data can be reasonably streamed over the internet, pulling only the points you need. 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. The EPT file can be used in Potree and QGIS to view the point cloud.\r\n \r\n \r\n download\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/10356/breaklines/index.html\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n Breaklines\r\n \r\n \r\n Link to the breaklines in Esri gdb and OGC GeoPackage formats.\r\n \r\n \r\n download\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/10356/supplemental/IN_DNR_Lidar_LidarMappingReport.pdf\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n Lidar Report\r\n \r\n \r\n Link to the lidar report.\r\n \r\n \r\n download\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n https://coast.noaa.gov/lidar/viewer/v/noaapotree.html?r=https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/entwine/geoid18/10356/ept.json\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n Potree 3D View\r\n \r\n \r\n Link to view the point cloud (using the Entwine Point Tile (EPT) format) in the 3D Potree viewer.\r\n \r\n \r\n download\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n https://coast.noaa.gov/dataviewer/\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n NOAA's Office for Coastal Management (OCM) Data Access Viewer (DAV)\r\n \r\n \r\n The Data Access Viewer (DAV) allows a user to search for and download elevation, imagery, and land cover data for the coastal U.S. and its territories.

Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification. The data was developed based on a horizontal projection/datum of NAD83(HARN), Indiana West Feet, and vertical datum of NAVD88 (GEOID18) Feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 2139 individual 1250 ft x 1250 ft tiles clipped to the DPA, as tiled Intensity Images and tiled bare-earth DEMs; all tiled to the same 1250 ft x 1250 ft schema.\r\n\r\nOriginal Dataset Ground Conditions: Lidar was collected in April 2024, while no snow was on the ground and rivers were at or below normal levels. Sanborn Map Company, Inc. established a total of 25 accuracy check points, 20 in Bare Earth and Urban landcovers (20 NVA points), 5 in Tall Grass and Brushland/Low Trees categories (5 VVA points), that were used to assess the vertical accuracy of the data.\r\n\r\nThis dataset was provided to the NOAA Office for Coastal Management (OCM) by the Indiana Dept. of Natural Resources to make the data available for bulk and custom downloads from the NOAA Digital Coast Data Access Viewer.\r\n \r\n \r\n To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and elevation modeling, etc. Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Intensity Images, Breaklines and Raster DEM. The purpose of these lidar data was to produce high accuracy 3D hydro-flattened Digital Elevation Model (DEM) with a 1 ft cell size.\r\n These lidar point cloud data were used to create intensity images, 3D breaklines, and hydro-flattened DEMs as necessary.\r\n \r\n \r\n Sanborn Map Company, Inc., Indiana Dept. of Natural Resources\r\n \r\n \r\n completed\r\n \r\n \r\n \r\n \r\n NOAA Office for Coastal Management\r\n \r\n \r\n \r\n \r\n \r\n \r\n (843) 740-1202\r\n \r\n \r\n \r\n \r\n \r\n \r\n 2234 South Hobson Ave\r\n \r\n \r\n Charleston\r\n \r\n \r\n SC\r\n \r\n \r\n 29405-2413\r\n \r\n \r\n \r\n coastal.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://coast.noaa.gov\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n NOAA Office for Coastal Management Website\r\n \r\n \r\n NOAA Office for Coastal Management Home Page\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA Office for Coastal Management\r\n \r\n \r\n \r\n \r\n \r\n \r\n (843) 740-1202\r\n \r\n \r\n \r\n \r\n \r\n \r\n 2234 South Hobson Ave\r\n \r\n \r\n Charleston\r\n \r\n \r\n SC\r\n \r\n \r\n 29405-2413\r\n \r\n \r\n \r\n coastal.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://coast.noaa.gov\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n NOAA Office for Coastal Management Website\r\n \r\n \r\n NOAA Office for Coastal Management Home Page\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n custodian\r\n \r\n \r\n \r\n \r\n \r\n \r\n notPlanned\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/10356/supplemental/in2024_cstline_m10356.kmz\r\n \r\n \r\n This graphic shows the lidar coverage for the 2024 lidar acquisition along the Indiana Lake Michigan coastline.\r\n \r\n \r\n kmz\r\n \r\n \r\n \r\n \r\n \r\n \r\n EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION\r\n \r\n \r\n EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n 17.0\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA\r\n \r\n \r\n CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > INDIANA\r\n \r\n \r\n VERTICAL LOCATION > LAND SURFACE\r\n \r\n \r\n place\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Location Keywords\r\n \r\n \r\n \r\n 20.8\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n LIDAR > Light Detection and Ranging\r\n \r\n \r\n instrument\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Instrument Keywords\r\n \r\n \r\n \r\n 17.2\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Airplane > Airplane\r\n \r\n \r\n platform\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Platform Keywords\r\n \r\n \r\n \r\n 17.2\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce\r\n \r\n \r\n dataCentre\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Data Center Keywords\r\n \r\n \r\n \r\n \r\n 2017-04-24\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n 8.5\r\n \r\n \r\n \r\n \r\n Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA)\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords\r\n \r\n \r\n GCMD Keyword Forum Page\r\n \r\n \r\n Global Change Master Directory (GCMD). 2025.

The following steps describe the Raw Data Processing process:\r\n 1) Technicians processed the raw data to LAS format flight lines using the final GNSS/IMU solution. This LAS data set was used as source data for lidar matching.\r\n 2) Technicians utilized commercial and proprietary software packages to analyze how well flight line overlaps match for the entire lift and adjusted as necessary until the results met the project specifications.\r\n 3) Once all lifts were completed with lidar matching, the technicians checked and corrected the vertical misalignment of all flight lines and also the matching between data and ground truth. The relative accuracy was less than or equal to 6 cm RMSEz within individual swaths and less than or equal to 8 cm RMSEz or within swath overlap (between adjacent swaths).\r\n 4) The technicians ran a final vertical accuracy check of the flight lines against the surveyed check points after the z correction to ensure the requirement of NVA = 19.6 cm 95% Confidence Level (Required Accuracy) was met. Point classification was performed according to USGS Lidar Base Specification, and breaklines were collected for water features. Bare-earth DEMs were exported from the classified point cloud using collected breaklines for hydroflattening.\r\n \r\n \r\n 2024-01-01T00:00:00\r\n \r\n \r\n \r\n \r\n \r\n \r\n LAS Point Classification: The point classification is performed as described below: \r\n\tBare-earth points are extracted from the point cloud using automated processes in Terrascan. Then the bare-earth surface is manually reviewed to ensure correct classification on the Class 2 (Ground) points. After the bare-earth surface is finalized, it is used to generate all hydro-breaklines through heads-up digitization. All Class 2 (Ground) lidar data inside of the Lake Pond and Double Line Drain hydro-flattened breaklines are then classified to Class 9 (Water) using LP360 functionality. A buffer of 1 ft was used around each hydro-flattened feature to classify these Class 2 (Ground) points to Class 20 (Ignored Ground). All Lake Pond Island and Double Line Drain Island features were checked to ensure that the Class 2 (Ground) points were reclassified to the correct classification after the automated classification was completed. No overlap points were classified or flagged, and all withheld points were flagged using Terrascan. All data was manually reviewed and any remaining artifacts removed using functionality provided by LP360, TerraScan and TerraModeler. Global Mapper was used as a final check of the bare-earth dataset. GeoCue was then used to create the deliverable industry-standard LAS files. Sanborn Map Company, Inc. uses proprietary software to perform final statistical analysis of the classes in the LAS files, on a per tile level to verify final classification metrics and full LAS header information.\r\n \r\n \r\n 2024-01-01T00:00:00\r\n \r\n \r\n \r\n \r\n \r\n \r\n Data was tested at 0.34 meter aggregate nominal pulse spacing and at 8.6 aggregate points per meter. The aggregate nominal pulse spacing was tested on classified tiled LAS using geometrically reliable first-return points. ANPS was tested using Delaunay Triangulation that produced average point spacing between all nearest neighbors.\r\n \r\n \r\n 2024-01-01T00:00:00\r\n \r\n \r\n \r\n \r\n \r\n \r\n The NOAA Office for Coastal Management (OCM) received 2139 LAS files from the Indiana Dept. of Natural Resources. The files were in Indiana State Plane West NAD83(HARN), US feet coordinates and the elevations were in NAVD88 (GEOID18) feet. The LAS files contain 7 classifications: 1 = unclassified; 2 = ground (or Bare Earth); 7 = low point (noise); 9 = water; 17 = bridges; 18 = high noise; 20 = ignored ground. The class 7 and 18 points also had the withheld bit set. OCM processed the 1, 2, 9, 17, and 20 point classes to the Digital Coast Data Access Viewer (DAV).\r\n\r\nOCM performed the following processing on the data for Digital Coast storage and provisioning purposes:\r\n\r\n1. The data were converted to laz format using laszip\r\n\r\n2. Internal OCM scripts were run to check the number of points by classification and by flight ID and the gps, elevation, and intensity ranges.\r\n\r\n3. Internal OCM scripts were run on the laz files to:\r\n\r\na. Convert from orthometric (NAVD88) elevations to ellipsoid elevations using the GEOID18 model\r\n\r\nb. Convert from IN State Plane West Zone 1302 (NAD83 HARN), US survey foot coordinates to geographic coordinates\r\n\r\nc. Convert from vertical units of feet to meters\r\n\r\nd. Filter points outside the elevation range of -100 feet to 6500 feet\r\n\r\ne.
