50031 tx2001_harris_m102_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed 2002-11-22 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. This data was acquired for use in the Tropical Storm Allison Recovery Project (TSARP). 10675 A footprint of this data set may be viewed in Google Earth at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/102/supplemental/tx2001_harris_m102.kmz Theme ISO 19115 Topic Category elevation Theme Surface Theme Terrain Office for Coastal Management Charleston SC Data Set None Planned LAS 1.2 Classes 1,2,7 Any conclusions drawn for the analysis of this information are not the responsibility of the Harris County Flood Control District, the Tropical Storm Allison Recovery Project, the Office for Coastal Management, or its partners.

The data was collected in October of 2001 using an Airborne LIDAR Topographic Mapping System (ALTMS). Flight altitude was approximately 915 meters, creating a data swath of approximately 550 meters. 2001-01-01T00:00:00 2 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. 2008-11-03T00:00:00 gov.noaa.nmfs.inport:50031 Anne Ball 2017-11-15T15:23:52 SysAdmin InPortAdmin 2022-08-09T17:11:37 2022-03-16 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
