Summary

Abstract: ABSTRACT: The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service (NOS), coordinates a network of geodetic-quality CORS stations that provide Global Positioning System (GPS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the United State and its territories. The positions of these CORS sites help define the National ...

Purpose: PURPOSE: NGDC archives the CORS data set as per the NOAA/NOS Records Disposition Schedule, section 1602-12.

Quality ATTRIBUTE ACCURACY REPORT: The carrier phase observations are accurate to a few centimeters, once biases have been removed.

LOGICAL CONSISTENCY REPORT: To become part of the CORS network, each site must pass through NGS' site criteria standards and maintain its integrity. Automated routines at NGDC pull data staged by NGS at regular intervals.

COMPLETENESS REPORT: Data ...

DISTRIBUTION LIABILITY: 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.
