Description:
Abstract:
This data set was received by the NOAA Coastal Services Center from
the Texas Natural Resources Information System.
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.
Purpose:
This data was acquired for use in the Tropical Storm Allison Recovery
Project (TSARP).

Process Step:
Process Description:
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.
