This paper presents an attempt to consider whether it is
possible to determine a geoid at the centimetre level in the
territory of Egypt based on recently available global and local
gravity field data. The paper has two main objectives. Firstly,
the paper overviews previously published geoid solutions,
while the second objective investigates the performance of
the recent global geopotential models (GGM) in Egypt.
The existing geoid solutions have illustrated that there
is an insufficient distribution of data which is sampled
inconsistently. At this time, data deficiency still exists, and to
overcome it, we have selected a "data window" and applied
the Least Square Collocation (LSC) technique. The outcome
from LSC was interesting and acceptable, and we obtained
a "sample" geoid that has a standard deviation of 11 cm for
the external control points.
