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

App Geodetic7parameters 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 datum to another. The Helmert transformation is also called a seven-parameter transformation

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

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

example
Ptn01 4229506.5980 1636778.2450 4469871.7560
Ptn02 4226053.0430 1639779.2820 4472044.3710
