2017 NOAA Ortho-rectified Below Mean High Water Color Mosaic of Boston, Massachusetts: Integrated Ocean and Coastal Mapping
Product
Dataset Identification:
Resource Abstract:
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 from 20170810 - 20170810 with an Applanix Digital Sensor System (DSS).
The original images were acquired at a higher resolution to support the final ortho-rectified mosaic.

description Mosaic's were generated from the color ortho-rectified imagery using OrthoVista. Pyramids are built in during this step. Mosaic
data have not been histogram stretched and only minimal color balancing has been performed. The images are in 8 bit RGB. The
DEM source is 30 meter posting USGS NED. Cubic convolution resampling method was used to create the final ortho-rectified
mosaic. Original image tiles are 2.5 km by 2.5 km squares.
AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy
evaluation Method Description
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.; Quantitative Value: 1.5 meters, Test
that produced the value: These data are accurate with a 95% circular error confidence level.

Completeness Commission
name Of Measure Completeness Report
evaluation Method Description
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.
ConceptualConsistency
name Of Measure Conceptual Consistency
evaluation Method Description
All rectified images were loaded in Global Mapper to view the entire project area for tone differences, complete coverage,
warping/smearing imagery due to inaccurate DEM, and any other obvious problems. All final tiles are reviewed for artifacts,
unblended seam-lines and warps or smears and then corrected using Photoshop.
Use Constraints: Disclaimer - While every effort has been made to ensure that these data are accurate and reliable within
the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions
in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed
or implied, nor does the fact of distribution constitute such a warranty.
