The Affine 4 parameters transformation

Don't forget to subscribe my youtube channel. Ne zaboravite da se prijavite kao pratilac na moj youtube kanal

The parameters are: two East/North translations, rotations, the scale factor and the rotation angle.

The Affine 4 parameters transformation is one of the possible methods to transform coordinates in plane. Mathematically, to transform the coordinates from one reference system to another, at least the coordinates of 2 points in both systems are needed

Even though 3 known points in both systems are sufficient to solve this transformation, it is obviously advised to use more points in order to have a more accurate calculation

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.
