Item Identification

Title: 2008 NOAA Integrated Ocean and Coastal Mapping (IOCM) LIDAR: New Hampshire
Short Name: ngs2008_nh_m99_metadata
Status: Completed
Publication Date: 2008-06-25
Abstract:

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

Sensing Division using an OPTECH ALTM system on June 8, 2008. The data includes topographic data in an LAS format file.

The NOAA Office for Coastal Management (OCM) processed the data to bare earth (class 2) and water points classified (class 9).

An automated filter was used, followed by semi-manual classification and bridge removal.

Purpose:

This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's IOCM (Integrated Ocean and Coastal Mapping)

initiative. 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:

10223

Supplemental Information:

Data include all lidar returns (first, second, third, and last) "Outliers" or "false returns"

(e.g., returns from birds, atmospheric particles, and/or system noise) may be present in the data.

Process Steps

Process Step 1

CC ID: 1146687
Description:

Data were processed to an initial LAS format using the ALTM DASHMAP 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: 2008-06-17 00:00:00

Process Step 2

CC ID: 1146688
Description:

The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity

and elevation measurements. OCM performed the following processing on the data to make it available within the LiDAR Data

Retrieval Tool (LDART):

1. The data were converted from UTM coordinates to geographic coordinates.

2. The LAS header fields were sorted by latitude and updated.

3. The data was filtered to eliminate outliers.

Process Date/Time: 2008-08-04 00:00:00

Process Step 3

CC ID: 1146689
Description:

Lidar data were processed to bare earth (class 2) and water points classified (class 9). An

automated filter was used followed by semi-manual classification and bridge removal.
