The data was collected in October of 2001 by Terrapoint USA, Inc. using an Airborne LIDAR Topographic Mapping System (ALTMS). Flight altitude was approximately 915 meters, creating a data swath of approximately 550 meters. The surface elevation value accuracy is better than 15 centimeters. The lidar points are unclassified. This data was acquired for use in the Tropical Storm Allison Recovery Project (TSARP). 20011007 20011105 Ground Condition Complete None -95.986334 -94.888765 30.186647 29.483833 ISO 19115 Topic Category Elevation None Bathymetry/Topography LiDAR Terrain Model Elevation Surface Laser None US Texas Harris County Houston None Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.

The Woodlands TX 77380 US 877-999-7687 Peggy.Cobb@terrapoint.com The NOAA Coastal Services Center (CSC) received the files in ASCII format. The data were in Texas State Plane Projection ADSZone 5401 (Texas South Central), NAVD88 vertical datum and the vertical units of measure were feet. CSC performed the following processing to the data to make it available within Digital Coast: 1. The data were converted from Texas State Plane East, ADSZone 5401 (Texas South Central) coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid99. 3. The vertical unit of measure for the data was converted from feet to meters. 4. The LAS data were sorted by latitude and the headers were updated. 20081103 Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) Coastal Elevation Mapping (CEM) Project Scientist Mailing and physical address

Charleston SC 29405-2413 843-740-1200 tcm@csc.noaa.gov The NOAA National Geophysical Data Center (NGDC) received Lidar data files on external harddrive. The disk contains LiDAR data from the NOAA Coastal Services Center. The data are currently being served via Digital Coastl at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are provided on this disk in LAS format. LAS format is an industry standard for serving LiDAR data. The data are exclusively in geographic coordinates, however, the datums used vary. Most are NAD 83, however some are in ITRF. Vertical systems include both ellipsoid (ITRF and NAD 83) and NAVD 88. For NAVD 88 values, Geiod 03 is primarily used; however, data received in NAVD 88 prior to 2003 was processed using Geoid 99. 20090720 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Grothe Mailing and Physical Address
