DNAG Gravity Data
The Decade of North American Geology (DNAG) gravity grid values, spaced at 6 km, were
used to produce the Gravity Anomaly Map of North America (1987; scale 1:5,000,000).
Considerable caution should be exercised when using these gridded data in regions
of sparse coverage (for example, deep oceanic areas). The spatial distribution of
the original data from which the grid was generated is shown on sheet 5 of the published
map. Note: There are no gridded data values for Mexico.

Supplemental Information |
Note that this Spherical Transverse Mercator projection is a unique projection used
for the DNAG map series. 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: -4480 kilometersThe Eastern-most boundary: 4500 kilometersThe
Northern-most boundary: 9280 kilometersThe Southern-most boundary: 700 kilometers
