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.
Ortho-rectified mosaic tiles are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data.
The ground sample distance (GSD) for each pixel is 0.30 m. The imagery was not tide coordinated at the time of acquisition. This data was flown from 12/4/2018-12/20/2018.

This data has been compiled to meet National Standard for Spatial Data Accuracy (NSSDA) ACCURACYr = 1.47m at 95% confidence level; 1)Actual RMSEr tested at 0.37m for UTM14N and 0.29m for UTM15N, 2)Actual Accuracyr NSSDA horizontal tested at 95% = 0.32m for UTM14N and 0.25m for UTM15N 3)Actual CE tested at 95% = 0.21m for UTM14N and 0.17m for UTM15N.
A complete iteration of processing (GPS/IMU Processing, Raw Ortho Data Processing, and Verification of Coverage and Data Quality) was performed to ensure that the acquired data was complete, uncorrupted, and that the entire project area had been covered without gaps between flight lines. No void areas or missing data exists.
Compliance with the accuracy standard was ensured by the placement of GPS ground control. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical bundle aerotriangulation adjustment in both UTM 14N and UTM15N. The residuals of the adjustment met the required standards for accuracy which are 1 part in 10,000 of the flying height for the horizontal position (X and Y) and 1 part in 9,000 or better of the flying height in elevation (Z). 2. The DTM (Digital Terrain Model) data was checked against the project control. The technician visited and confirmed the accuracy of the project mass points during initial compilation. 3. Any topographic data was checked for edge match, consistency of attribution, and cartographic quality through visual inspection. 4. Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality.
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.

The full resolution aerial imagery was color balanced and mosaicked inside of Inpho’s Orthovista platform. The imagery was radiometrically balanced one flight line to another using the rectified ADS 16-bit 4 band (RGB-IR) imagery. No individual manipulation took place with the near-infrared band to maintain as much band integrity as possible. Once the imagery was processed through Inpho’s workflow Fugro Land imported the Orthovista output into their proprietary image database software and completed any additional image feature cleanup. Fugro Land created a Tone Contrast Curve (TTC) to complete the 16-bit to 8-bit image conversion. The final image format delivered was Stripped TIFs that were geo-referenced and accompanied by TIF World Files.

Under Fugro’s direction, all surveying activities were performed by Fugro's approved ID/IQ subcontractor Terrasurv, Inc. A total of 20 ground control points to support the lidar collection, along with 35 checkpoints were collected. The National Spatial Reference System (NSRS) was used to provide control for the network. Two Continuously Operating Reference Stations (CORS) were included in the network, as well as thirteen existing NSRS benchmarks. The horizontal datum was the North American Datum of 1983 – NAD83 (2011), epoch 2010.0.
