App is developed for the computation of the 7 parameters from identical points

Geodetic7parameters App is developed for the computation of the 7 parameters of the 3D similarity transformation between geodetic reference frames, calculates from identical points in different Geodetic Reference Systems exact parameter sets
for the spatial Helmert / Bursa-Wolf Seven Parameter Transformation

Geodetic7parameters from identical points - The Helmert transformation is a transformation method within a three-dimensional space. It is frequently used in geodesy to produce distortion-free transformations from one date to another. The Helmert transformation is also called a seven-parameter transformation

I am adding SD card (storage) and my permission code, but whatever and recommended to check SD card (storage) permission. Go to settings, app, find Geodetic7parameters app and allow SD card (storage) permission.

Input coordinates must be only in Cartesian format: name X Y Z (system A and system B)

example
Ptn01 4229506.5980 1636778.2450 4469871.7560
Ptn02 4226053.0430 1639779.2820 4472044.3710
