2005 US Army Corps of Engineers (USACE) Post-Hurricane Katrina LiDAR: Mississippi
and Western Alabama
LiDAR data was acquired for the U.S. Army Corps of Engineers (USACE), Mobile District
in September-October 2005 along the coastline of Hancock, Harrison, Jackson counties
in Mississippi and Mobile County in Alabama from the land water interface (shoreline)
to the north Right of Way of Interstate-10. The LiDAR DEM was delivered as first return,
last return, bare earth, and water delivery in LAS format. Contract Number: W91278-04-D-0001/0003
EN. Project Number: C-05-054. Contractor: R&M Consultants, Inc., Anchorage, AK. Subcontractor:
Woolpert, Inc., Dayton, OH.

| Processing Steps
- The NOAA Coastal Services Center (CSC) received files in LAS format. The files contained
lidar intensity and elevation measurements. CSC performed the following processing
on the data to make it available within the Lidar Data Retrieval Tool (LDART): 1.
The las files were sorted by latitude and the las header fields were updated. For
data managment purposes, the Coastal Services Center converted the data from NAVD88
elevations to ellipsoid elevations using Geoid 03.
- The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp
transfer from the NOAA Coastal Services Center. The data are
currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/.
The data can be used to re-populate the system. The data are archived in LAS
or LAZ format. The LAS format is an industry standard for LiDAR data developed by
the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless
compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The
data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data
are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for
the ability to apply the most up to date geoid model when transforming to orthometric
