Maine Bouguer Gravity GridEntry ID: gov.noaa.ngdc.G01403
Abstract: A 2 kilometer Bouguer anomaly grid for the state of Maine. Number of columns is 197 and number of rows is 292. The order of the data is from the lower left to the right and then up one row.
Purpose: To provide easy access to global and regional gravity data and related models for scientific studies.
SUPPLEMENTAL INFORMATION: 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: -204 kilometersThe Eastern-most boundary: 188 kilometersThe Northern-most boundary: 5622 kilometersThe Southern-most boundary: 5040 kilometers

Quality ATTRIBUTE ACCURACY REPORT: 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.
LOGICAL CONSISTENCY REPORT: Not available
COMPLETENESS REPORT: Not available
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.
