Swapped X and Y coordinates in gamma adjustment #158

Closed hblGP closed 3 years ago

hblGP commented 3 years ago

Hi,

When doing an 3D/horizontal adjustment I can see that in the resulting log file, the X and Y coordinates has been swapped around. I think this is mainly an error in the log file as the coordinates are correctly updated, see attached image.

???
Easting - who is this [X/Y]?
Northing - who is this [X/Y]?

zsiki commented 3 years ago

Gnu Gama uses the surveyors' coordinate system (as we do in Hungary or Germany) Y is easting and X is northing. The long log message is generated by GNU Gama, GeoEasy only displays it. So I can't solve it. You may ask GNU Gama developers ...

@zsiki Thank you for the explanation, of course that is the case. I've never worked with a left-handed coordinate system and didn't know that there may be different conventions for determining which direction the x and y coordinates goes. You get smarter every day.
