The necessity of classifying the transformations between coordinates referring to two different datums arises, on the one hand, from the diversity and the co-existence of mathematical models and, on the other hand, from the appearance of new standards of accuracy and new applications. The first step taken in the evaluation of the numerous projection and transformation models was to order them according to the criteria originating from the choice of the horizontal geodetic datum. A comparison of the geocentric and topocentric sets of datum position parameters shows the strong connection between the ellipsoidal and spatial models. Using the theory of mapping the effects on the elements of length and angle resulting from the transformation between coordinates of two different datums are clarified. Then cross connections, which, above ail, highlight the common factors of the two-dimensional and three-dimensional models, are established. A consideration of the reduction of distances and azimuths belonging to geodesy curves, which occur during spatial transformation between coordinates of two different datums with topocentric sets of datum position parameters, leads by means of the Helmert ellipsoid-to-ellipsoid mapping to the same geodetic coordinate additions, which also result from the comparable spatial model. By examining the accuracy, a statement about the numerical efficiency of the various groups of models can then be made. For this, rigid techniques are established, taking the current arithmetic algorithms and the criteria of structured programming into account and these are then applied to numerical calculations of comparison.
