    • 2018 NOAA NGS Ortho-rectified 4-band Mosaic of Texas: Galveston to Mustang Island

    Metadata Updated: October 31, 2024

    This data set contains ortho-rectified mosaic tiles, created by Fugro in support of the national shoreline mapping program for NOAA NGS. The source imagery was acquired using an ADS100 pushbroom camera. The original images were acquired at a higher resolution to support the final ortho-rectified mosaic.

    Lineage Fugro collected ADS derived orthos in December 2018 for the TX1803-TB-C AOI with 30cm GSD. Data was collected when environmental conditions meet the criteria specified. Digital imaging shall not be conducted when clouds or cloud shadow obscure the land-water interface or features of navigational significance in the scene. The landwater interface shall not be obscured by snow, ice, smoke, haze, etc. Storm systems and events (e.g. hurricanes, northeasters, and frontal boundaries) that may cause an increase in water levels, tidal heights, and wave activity shall be avoided. Efforts to avoid sun glare shall be taken. Time of day for digital camera imagery is determined by the sun angle which shall not be less than 25 degrees above the horizon at the time of exposure. If imagery is collected between the months of November and February, the sun angle requirement shall not be less the 20 degrees. This data was collected in 22 planned lines, 31 altogether with reflights. Lines are presented below as Line Number - Date Acquired - Universal Time Coordinated (Zulu Time) of Line Beginning - Universal Time Coordinated (Zulu Time) of line Ending: 1 - 12/10/18 - 16:26:24 - 16:49:17 2 - 12/10/18 - 19:48:43 - 20:10:26 3 - 12/13/18 - 17:03:08 - 17:16:02 3 - 12/20/18 - 16:06:20 - 16:15:42 4 - 12/13/18 - 17:35:56 - 17:37:37 4 - 12/13/18 - 17:45:16 - 17:54:56 4 - 12/20/18 - 16:21:41 - 16:29:49 5 - 12/13/18 - 17:58:52 - 18:06:40 5 - 12/20/18 - 16:33:24 - 16:41:28 6 - 12/13/18 - 18:11:06 - 18:18:49 6 - 12/20/18 - 16:44:33 - 16:51:21 7 - 12/13/18 - 18:22:40 - 18:30:41 7 - 12/13/18 - 18:35:58 - 18:37:14 7 - 12/20/18 - 16:55:37 - 17:09:27 8 - 12/13/18 - 18:40:13 - 18:47:22 9 - 12/10/18 - 16:08:54 - 16:11:52 10 - 12/10/18 - 15:39:54 - 15:48:44 11 - 12/10/18 - 17:29:37 - 17:35:44 11 - 12/10/18 - 19:03:00 - 19:29:04 12 - 12/04/18 - 16:35:38 - 16:44:17 13 - 12/04/18 - 16:22:42 - 16:30:50 14 - 12/04/18 - 16:50:50 - 16:54:15 15 - 12/04/18 - 16:59:29 - 17:01:15 16 - 12/10/18 - 16:57:30 - 17:25:21 16 - 12/10/18 - 17:38:40 - 17:39:40 17 - 12/10/18 - 15:13:52 - 15:34:39 18 - 12/04/18 - 15:07:27 - 15:11:37 19 - 12/04/18 - 15:17:54 - 15:31:54 20 - 12/04/18 - 15:36:44 - 15:51:41 21 - 12/04/18 - 15:59:03 - 16:02:00 22 - 12/04/18 - 16:05:42 - 16:07:28
