Andew,
visually the difference between your image and the one generated on my
PC are almost indistinguishable (no spatial shift at least). Please
submit a PR adding your checksums as alternate accepted ones. You may
just remove the "if sys.platform == 'darwin'" case. Hopefully adding
your checksums should fix the OSX CI too

Andrew,
This could be due to the PROJ version, but as I'm running
with 8.0 too (and one of the CI config runs PROJ master), I
suspect you just need to install the "conus" grid for NAD27
to WGS84 transformations into {proj_prefix}/share/proj .

I have PROJ_NETWORK set to ON. I was under the impression that
this would cause PROJ to find whatever grids shift files it
needed at runtime. Is there more configuration that's necessary
to get this to happen or do I misunderstand the PROJ_NETWORK setting?
That should be fine. Actually I was wrong. This test case doesn't
involve any datum shift / grids as it is EPSG:4326 to EPSG:3857
reprojection.
That might then just be a subtle different rounding issue in
computations in GDAL and/or PROJ, or more likely, due to using a
different JPEG library as this test case involves JPEG
compression. If that was the case, you might add your checksums as
an alternative expected output. We do that in a number of places.
Looking a few lines before the failure, I actually see that the CI
got that issue and we worked around it with:
if sys.platform == 'darwin' and gdal.GetConfigOption('TRAVIS',
None) is not None:
assert got_cs != [0, 0, 0]
else:
Could you run
gdal_translate ../autotest/gdrivers/data/small_world.tif out.tif
-of COG co TILING_SCHEME=GoogleMapsCompatible -co COMPRESS=JPEG
and attach the resulting file ?
Thanks,
