  In this paper a new Geophysical gravimetry approach is presented, which is
based on satellite imagery in remote sensing. The method uses a satellite
image, together with a set of points in the image the gravity values of which
are known. Template-based spheroidal spline method of interpolation is used to
constitute a system of equations to find the values of gravity at other points
in the image. A real case study is presented for the Qom region in Iran. Values
of gravity are determined from the Landsat satellite image for this region,
using 9 points in the image whose gravity values are known. Reference ellipsoid
gravity values, which are based on coefficients derived from satellite
gravimetry, are computed for this region, as well. Comparison between gravity
values derived from Landsat image and those from reference ellipsoid shows that
the standard deviation of the results is around 6.71 milli Gal, with the
maximum of differences being 35 milli Gal.
