Description:
This geoid has
been computed for the whole of Sudan,
ranging from 4° N to
24° N in latitude and
22° E to 38°
E in longitude. The EGM96 geopotential
model truncated to degree and order 70
was combined with surface gravity data
and modified Stokes’s kernel to generate
the geoid file. The surface data consist
of 30' x 30' and 10' x 10' mean gravity
anomalies. Comparison of the gravimetric
geoid with the Doppler/levelling
derived geoidal heights of 98 stations
all over Sudan shows that the absolute
agreement with respect to the
Doppler/levelling datum is generally
better than 1.43 m RMS.
