Item Identification

Title:	2001 HCFCD Lidar: Harris County (TX)
Short Name:	tx2001_harris_m102_metadata
Status:	Completed
Publication Date:	2002-11-22
Abstract:	This data set was received by the NOAA Office for Coastal Management 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).
Notes:	10675

Process Step 2

CC ID: 1132237

Description:	The NOAA Office for Coastal Management (OCM) 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. OCM 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.
