Hi Joris,
The (Spherical) Mercator projection has huge disturbances in size the
further you get from the equator. Try usiing the national projection for
Portugal?
Good luck,
Raymond

Hello
I have 2 point in Portugal
my project CRS is pseudo Mercator (EPSG 3857)
When I create a buffer of 30 km around my points layer cars is also EPSG 3857),
I get Two nice circles (layer also CRS 3857). When i measure the circles, they
are 45 km in diameter. What can be wrong?
What settings shouldI in general use for the measuring tool?
thanks for your comments
Joris
