Re: [Qgis-user] How to define which CRS to use?
Hi Nicolas, thanks for your input. To my knowledge, feet where never used as a unit in former Soviet Union. I di’d’nt know that there were crs’ses in feet at all. I will give it a try. thanks Joris Op 29-apr.-2015, om 23:38 heeft Nicolas Cadieux nicolas.cadi...@archeotec.ca het volgende geschreven: What if the coordinate where in feet instead of meters?

BINGO! thanks a lot, Redoute. Seems correct. How did you do that, just trial and error until something came up?
