In addition to giving the Bounding Coordinates in latitude and longitude, the limits of coverage for the gridded and projected data sets are also given in units of measure of the projection. This is usually the distance from a central meridian (the x-coordinate), or base latitude (the y-coordinate), in meters or kilometers of the given projection. For this data set those boundaries are:The Western-most boundary: -2574 kilometersThe Eastern-most boundary: 2622 kilometersThe Northern-most boundary: 5623 kilometersThe Southern-most boundary: 2539 kilometers

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

Horizontal Positional Accuracy Report
Horizontal accuracy varies from source contributor to source contributor. However, horizontal positions are usually taken from topographic maps of the area being surveyed. Accuracy may range up to +/- 100 feet.
Vertical Positional Accuracy Report
Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.

Quantitative Attribute Accuracy Assessment
Statistical analysis.
Gravity data values are the result of the measurement of small variations in thegravitational field of the Earth. The magnitudes and ranges of these variations are well known in the potential field discipline.
meters
Variable: the average acceleration on the Earth's surface is about 980
centimeters per second squared, which is equal to 980 gals, but increases by about
1/2 percent from equator to pole.
All data were processed by the source before being forwarded to the National Geophysical Data Center
