Title: 2018 NOAA NGS Ortho-rectified Near-Infrared Mosaic of Sacramento, CA
Short Name: CA1806_NIR
Status: Completed
Creation Date: 2018-10-28
Publication Date: 2018-12-12
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 20181028 - 20181028 with an Applanix Digital Sensor System (DSS). The original images were acquired at a higher resolution to support the final ortho-rectified mosaic.

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 0.50m. The imagery was not tide coordinated at the time of acquisition. 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.

Data Quality

Accuracy:

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

Quantitation Limits:

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.

Process Steps

Process Step 1

CC ID: 800913
Description:

Mosaic's were generated from the near-infrared 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. 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. 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.
