Dear all,
I calculate area values for counties in Alaska. The layer and the
project is in EPSG:2964 - NAD27 / Alaska Albers. However, If I switch
"transformation on the fly" on I get values in square-meters. If I
switch it off I get squarefoot, which is correct because the unit for
EPSG:2964 - NAD27 / Alaska is Foot_US.
So where are the square meters based on and what drives the calculation,
the layer CRS or the project CRS.
Thank you
Cheers
Klaus
