Item Identification

Title: U.S. Coastal Lidar Elevation Data
Short Name: ocm_lidar_holdings_metadata
Status: In Work
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 in a single format, projection, and datum.

Purpose:

Lidar data is used to study the surface of the earth for elevation, erosion, inundation, flooding, and coastal hazards applications.

Lineage

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.
