Full Citation Examples
Many different partners and groups, and several Center-led data projects, have contributed to the lidar data collection housed and distributed by the NOAA Office for Coastal Management. The data span more than two decades and were collected using many different sensors. The collection includes data from topographic and bathymetric lidar sensors. Data are available for all of the coastal states and range from shoreline strips to full county coverage. The products have been delivered to the Center in various formats, projections, datums, and units. Once received, the data are reviewed, checked for errors, and standardized to LAZ format, geographic coordinates and ellipsoid heights in meters. Data are on a NAD83 or ITRF realization depending upon the collection specifics.
Distribution Information
-
SpatioTemporal Asset Catalog (STAC) for datasets that are in entwine point tile (EPT) format. Not all datasets in this collection are in EPT format. In particular, most topobathy datasets are not because EPT does not properly represent the classification numbers used for bathymetry points in the ASPRS LAS topobathy domain profile.

Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.

| Abstract: |
Many different partners and groups, and several Center-led data projects, have contributed to the lidar data collection housed and distributed by the NOAA Office for Coastal Management. The data span more than two decades and were collected using many different sensors. The collection includes data from topographic and bathymetric lidar sensors. Data are available for all of the coastal states and range from shoreline strips to full county coverage. The products have been delivered to the Center in various formats, projections, datums, and units. Once received, the data are reviewed, checked for errors, and standardized to LAZ format, geographic coordinates and ellipsoid heights in meters. Data are on a NAD83 or ITRF realization depending upon the collection specifics. |
| Purpose: |
Lidar data is used to study the surface of the earth for elevation, erosion, inundation, flooding, and coastal hazards applications. |

Process Steps
Process Step 1
| Description: |
Lidar data are obtained from another source or through NOAA contract. Information about the data is gathered, usually from metadata and project reports from the lidar provider. The primary information necessary includes: 1) projection 2) datums 3) geoid model 4) acquisition dates 5) units 6) classification scheme 7) vertical accuracy |

| Phone (Voice): | (843) 740-1202 |
| Email Address: | coastal.info@noaa.gov |
Process Step 2
| Description: |
Data are standardized to geographic coordinates of the horizontal datum they originated in. Vertical values are converted to ellipsoid heights in meters by reversing the datum operation that was originally applied. Data are converted to LAZ format if they are not already in it. |

| Phone (Voice): | (843) 740-1202 |
| Email Address: | coastal.info@noaa.gov |
Process Step 3
| Description: |
Data are ingested into the Digital Coast Data Access Viewer. This includes: 1) verification that the point classifications found match the expected classifications based on the metadata or reports. 2) data fall within the expected bounds. 3) vertical ranges are recorded for each data tile and point class. 4) geographic bounds for each tile are recorded. 5) point classification table used is recorded. |
