Hi Matt,
The definitions are correct. For the union you want a rectangle (or polygon)
that's larger than the input, indeed. But you want the smallest of those
rectangles, because there's an infinity of them. The larger ones would cover an
arbitrary area of the plane (or the globe, if you want).
To my mind the outputs of Union should be the largest extent area and Intersect
is the smallest extent area. However any explanation in words alone will always
have some ambiguity. It can't be avoided.

clear in this exam
Hi, thanks again for the explanation
I uploaded the tif file I was trying to render here:

3.4.1 a quite a while ago, and I am wondering how it can work for all other tif
Hi,
According to the migration guide, this is only relevant for OSRImportFromEPSG,
SetWellKnownGeogCS and SetFromUserInput. But then again, you were using the
equivalent of OSRImportFromWkt.
I never noticed any issues when using spatial references loaded from existing
rasters, but you might wa
Thanks very much, I would never have figured that out myself.
Just to make it clear I should add this flag on all OGRSpatialReference or only
when it is loaded with importFromWkt ?

Hi Philippe,
The new behaviour is correct. See

for the axis order issue, a change made in GDAL 3.0. You can find a solution

Hi,
I have an app build against GDAL 3.4.1 and PROJ6, and the same app build
against GDAL 2.1.3 and PROJ4. They are not giving the same result when using
OGRCoordinateTransformation.

Hi there! Thanks, everyone for your help and recommendations provided.
Even, I wasn't aware of that, as many other things I see. I thought that It
could be translated directly
