red-lines - original scraps just rotated and scaled
blue-lines - scraps adjusted to survey stations (before processing joins)

red points - original positions of survey stations
yellow points connected by yellow line - original position of two points in scrap with maximal distortion
black points connected by black line - final position of two points in scrap with maximal distortion
yellow lines connecting black and yellow points indicate how these pointe were shifted.

If there is only one black point -> two stations with different names at one place.

Easiest way how to trace stations is to put -name in the search field. Then click "Find first" and then "Find next" and trace station after station, whether it has correct position.
