Title: U.S. Coastal Lidar Elevation Data - Including The Great Lakes And Territories, 1996 - Present
Short Name: NGDA OCM lidar holdings parent
Status: On Going
Creation Date: 1999
Revision Date: 2023-09-01
Publication Date: 1999
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.

Description:

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.

Data Management

Have Resources for Management of these Data Been Identified?: Yes
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: No
Actual or Planned Long-Term Data Archive Location: NCEI-NC
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

Source data are backed up to the Azure cloud or the received hard drives are stored. After ingestion, data are also backed up to Azure on a weekly basis.

Lineage

Lineage Statement:

Data are received from contracted collections, other NOAA offices, or other federal, state, or local agencies. The data are standardized for ingest into the Digital Coast Data Access Viewer and made available to the public.

Process Steps

Process Step 1

CC ID: 989103
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

CC ID: 989104
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

CC ID: 989105
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.
