Geodetic 9 Parameters Transformation

The Estimation of Geodetic Datum Transformation Parameters

App Geodetic9parameters is developed for the computation of the 9 parameters of the 3D similarity transformation between geodetic reference frames, calculates from identical points in different geodetic Reference Systems (3 translations, 3 rotations, 3 scales).

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 geodetic9parameters and allow SD card (storage) permission.

Input coordinates must be only in Cartesian format : name Y X Z (system A and system B). Download example files at the end of the text.
