2018 NOAA Ortho-rectified Color Mosaic of Newport, Rhode Island

This data set contains ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative. The source imagery was acquired on 20180505 with a Trimble Digital Sensor System (DSS). 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 0.50 m. The imagery was not tide coordinated at the time of acquisition.

Users must assume responsibility to determine the usability of these data. These photographs were obtained for use by NGS during the course of its development of potential final products to fulfill its statutory mission. Although NGS is making these photographs available to others who may find the photographs of value, NGS does not warrant, endorse, or recommend the use of these photographs for any given purpose. NGS is providing these photographs "as is," and NGS disclaims any and all warranties, whether expressed or implied, including (without limitation) any implied warranties of merchantability or fitness for a particular purpose. In no event will NGS be liable to you or any third party for any direct, indirect, incidental, consequential, special, or exemplary damages or lost profits resulting from any use or misuse of these data. Any conclusions drawn from the analysis of this information are not the responsibility of NOAA, the National Geodetic Survey, the Office for Coastal Management, or its partners.

The extent of image coverage is limited to the acquired flight lines which were planned to map the shoreline and therefore may not include all areas within the bounding coordinates.

Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.

The accuracy of the data is plus or minus 1.5 m at at the 95% circular error confidence level.

The horizontal positional accuracy and the assurance of that accuracy are dependent upon the accuracy of the data inputs to the rectification process. These data inputs include the digital elevation model (DEM), accuracy of control, and methodology used to georeference the imagery that meet NOAA's Coastal Mapping Program standards.
