Title: 2011 NOAA National Geodetic Survey (NGS) LIDAR of North Carolina: Hurricane Irene Emergency Response Mapping Product
Status: Completed
Publication Date: 2011
Abstract:

These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using

a Riegl Q680i-D system. The data were collected August 28 and 29, 2011 after landfall of Hurricane Irene in Dare and Carteret counties

in North Carolina. The data includes topographic data in an LAS 1.2 format file classified as unclassified (1), ground (2),

and water (9) in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards.

This data set also includes lidar intensity values and encoded RGB image values.

Purpose:

This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's Emergency Response Program. It is not intended for mapping,

charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar.

Notes:

10224

Supplemental Information:

Data include all lidar returns. Outliers or false returns (e.g., returns from birds, atmospheric particles, and/or system noise) may be

present in the data. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted

that not all water returns were correctly classified; therefore the ground classification could proceed into water bodies, and should be

removed by the user.

Process Steps

Process Step 1

CC ID: 1132548
Description:

Data were processed to an initial LAS format using the Riegl RiProcess software. The Applanix POSPac software was utilized for GPS and

inertial processing, and Terrasolid software for data visualization, 3D editing, and export to final LAS file. Data were processed in

NAD83 horizontal and vertical datum.

Process Date/Time: 2011-10-06 00:00:00

Process Step 2

CC ID: 1132549
Description:

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained lidar elevation, intensity,

and RGB image values. The data were in UTM Zone 18N projection. OCM performed the following processing for data storage and

Digital Coast provisioning purposes:

1. The data were converted from UTM Zone 18N coordinates to geographic coordinates.

2. The data were filtered to remove outliers.

3. The LAS data were sorted by time and the headers were updated.

4. The LAS files were compressed to LAZ files using laszip version 111006.
