Which of the following describes the model used by the Geodetic Extender?
-
Flat earth
-
E-D square
-
Trapezoidal
-
Round Earth
D
Correct answer
Explanation
The DB2 Geodetic Extender uses a Round Earth model (spherical model) for spatial calculations rather than flat-earth approximations. This is essential for accurate geographic and geodetic computations over long distances where Earth's curvature matters. Geodetic coordinate systems account for the Earth's spherical shape, unlike planar projections that distort distance and area measurements.
