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: -2934 kilometersThe Eastern-most boundary: 2978 kilometersThe Northern-most boundary: 5979 kilometersThe Southern-most boundary: 2179 kilometers Gravity grid value Value, in milligals of an observed gravity station value, after various corrections have been applied to the value. 3687 -5729 true Binary DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce User Services 303-497-6826 303-497-6513 325 Broadway Boulder CO 80305-3328 USA ngdc.info@noaa.gov 8am-5pm, Monday through Friday distributor Depends on the data set Ordering Instructions: Prepay by check, money order or bank card.

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. Not available Not available Quantitative Attribute Accuracy Assessment Statistical analysis. Gravity data values are the result of the measurement of small variations in the gravitational 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.
