Description:
Abstract:
This data set contains ortho-rectified mosaic tiles at 0.35m GSD created for NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative in Hurricane Sandy coastal impacted areas. The source imagery was acquired on 20140818. Each orthoimage provides imagery over a 1400 by 1400 meter block on the ground. There is no image overlap between adjacent files.
Purpose:
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.
Supplemental_Information:
The ground sample distance (GSD) for each pixel is 0.35 m. Imagery is not tide coordinated.

Data_Quality_Information:
Logical_Consistency_Report:
All GeoTIFF tagged data and image file sizes are validated using commercial GIS software to ensure proper loading before being archived. This validation procedure ensures correct physical format and field values for tagged elements. Seamlines and tile edges are visually inspected. Seamline mismatches are not corrected unless the overall displacement exceeds one meter.
Completeness_Report:
Orthoimages are visually inspected for completeness to ensure that no gaps or image misplacements exist within and between adjacent images. These images are derived by mosaicking multiple images to ensure complete coverage. Source imagery is cloud free. Photography was flown during leaf-off in deciduous vegetation regions. Coastal areas and international boundary regions may have areas without images (void areas) in parts of the coverage. These void areas have a radiometric value of either zero (black) or 128 (uniform gray).

Process_Description:
Digital aerial imagery was obtained using a large format Z/I Digital Mapping Camera system (DMC) equipped with Airborne GPS/IMU covering the AOI. A total of 9 flight lines with 239 frames were collected in fall 2014 in multi-spectral (RGB and NIR) 16 bits per band format. The imagery was acquired with a 120mm focal length at an altitude above mean terrain of 3,360' to yield a raw pixel resolution of 0.35m. The imagery was collected during leaf off conditions in early 2014 under conditions free from clouds and cloud shadows, smoke, fog, haze, light streaks, snow, ice on water bodies, foliage, flooding, and excessive soil moisture. The sun angle threshold was 30 degrees. The imagery consisted of panchromatic, blue, green, red and near infrared bands. The three color bands and near infrared bands have been pan sharpened and archived as frame imagery. Ground based photo control points were established throughout the area of interest using a combination of conventional and GPS survey methods in order to support softcopy aerotriangulation and photogrammetric mapping meeting the accuracies specified in this Scope of Work. This control supplemented the exposure station control obtained from the onboard Airborne Global Positioning System (ABGPS) and Inertial Measurement Unit (IMU). Photo control points established for this project have a combined local and network accuracy at 95% confidence of less than or equal to five (5) centimeters horizontally and vertically as determined by the residuals of the network adjustment. Utilizing all four pan-sharpened bands [blue (B), green (G), red(R) and near infrared (IR)] digital orthorectification was performed using cubic convolution algorithms resulting in a spatial and radiometric transformation of the digital image from line/sample space into UTM Zone 19. The interior and exterior orientation parameters were used to project each pixel into the ground coordinate system, while the ortho grade DEM/DTM was used to correct for relief displacement. Radiometric correction software and techniques were used to create orthophoto files that minimize the appearance of image seams and without loss of feature signature. Orthophotos are checked for geometric accuracy, image quality and tonally balanced to produce a uniform contrast and tone across the entire project. The individual overlapping orthophoto frames were mosaicked together and the final tiles were extracted from the image set to a 1,400 x 1,400 meter tiling scheme consisting of 269 individual ortho tiles. Delivery included digital ortho photos at a 0.35m pixel ground sample distance in 8 bit, 4 band (RGB and NIR) uncompressed GeoTIFF. The ortho photos meet a horizontal accuracy of +/- 1 meter or less RMSE when compared to higher accuracy check points based on NSSDA testing standards.

Process_Description:
All GeoTIFFs for coastal RI were downloaded from the NOAA Digital Coast Data Access Viewer FTP site. Using Global Mapper version 17, these images were added to a map catalog, reprojected from UTM Zone 19N to Rhode Island State Plane NAD83 feet and then clipped to new tile boundaries. These were then used as the input data to create JPEG2000 files using a Global Mapper script. Both GeoTIFF and JP2 have target compression ratio of 1:10, and the tiling scheme is 10,000ft x 10,000ft. Tile names are based on coordinates of the southwest corner of the given tile. Individual tiles overlap their neighbors by 5 pixels, and no original data was clipped away. Original metadata written by NOAA NGS; minor updates and changes to content were made by RIGIS, resulting in this project-wide metadata record.
