introduces a small error. At 6,378 m elevation, the radius and surface distance is increased by 0.001 or 0.1%. 
Because the earth is not flat, the precision of the longitude part of the coordinates increases 
the further from the equator you get. The precision of the latitude part does not increase so much, 
more strictly however, a meridian arc length per 1 second depends on the latitude at the point in question. 
The discrepancy of 1 second meridian arc length between equator and pole is about 0.3 metres because the earth 
is an oblate spheroid.`
