SEVENPAR (Deutsch)
Purpose of the program SEVENPAR is to produce a set with seven Helmert transformation parameters valid for an specific area, in which then arbitrary points can be transformed from one coordinate system into another with high accuracy. The Helmert transformation parameters are computed with a... Cartesian coordinates or geographical coordinates with ellipsoidal height using the ellipsoid dimensions are suitable. ... The coordinates of the identical points are tested intensively on outliers and deviations by different statistic procedures.
