gdalinfo on your local machine is correctly picking up the NETCDF driver whereas the version with vsicurl seems to be using the HDF5 driver, which is a fallback option when the file is not recognized by the NETCDF driver. Could you provide the output of the gdalinfo vsicurl version with CPL_DEBUG=ON set.
/vsicurl/ support in the netCDF driver requires a recent enough version of libnetcdf which installs the netcdf_mem.h header file

@rouault
We were running against libnetcdf v4.3.3.1 which lacked the netcdf_mem.h header file. I built v4.6.2 by hand and confirmed that netcdf_mem.h is now there. I am still seeing GDAL selecting the wrong driver over vsicurl. An example is in the response above.
Did you 'make clean' after running GDAL configure again ? And do you run a recent enough Linux kernel ( >=4.3) so as to see "userfaultfd support: yes" at the end of ./configure output ?
@rouault
I did a fresh build in a new container for the new version of netcdf.
I see:
userfaultfd support: yes
about 10 lines from the end of my ./configure output.
Does gdalinfo --format netcdf | grep Virtual
report Supports: Virtual IO - eg. /vsimem/
?
It does for me and gdalinfo /vsicurl/https://s3.amazonaws.com/idixon/S1-GUNW-D-R-042-tops-20190103_20181210-140759-38619N_36645N-PP-24f6-v2_0_0.nc
opens with the netCDF driver
It does not. I'll investigate. Thanks!
what does uname -a
report ? The Linux kernel header might be present but if the runtime version number is not >= 4.3, then it is not available at runtime

hum, well,then you can then try running under gdb, and set a break point on CPLIsUserFaultMappingSupported. It should be called and return true
Ok, I think that's my next step. Thanks for the help @rouault !
@rouault
The plot thickens! I tried building on another architecture and looked though the logs more carefully this time. In the gdal configure I noticed:

I'm fairly certain I built netcdf correctly. Do you think this could be an indication that build is getting fouled?
I'm fairly certain I built netcdf correctly. Do you think this could be an indication that build is getting fouled?
absolutely. It would seem that netcdf_mem.h cannot be included alone. Does "NetCDF has netcdf_mem.h: yes" appear at the end of configure output ? I'd bet not If so, try
echo '#include <stdio.h>' > conftest.c
echo '#include <netcdf_mem.h>' >> conftest.c
gcc -c conftest.c
(I haven't tested with netcdf 4.6, so it might be possible that the header in this version depends on other headers)
@rouault
It gets worse.
I rolled back to netcdf version 4.6.0 after seeing a post describing a the same problem with v4.6.2 in another project. When I configured GDAL this time everything looks peachy:

What version of NETCDF are you running?
What version of NETCDF are you running?
hum, I've a weird setup currently... It appears I'm building against netcdf 4.4 from Ubuntu 16.04 but I manually added netcdf_mem.h in /usr/include, but at runtime I'm linking against a manually compiled netcdf 4.5.0, and somehow that works...
@idixon ... do the debug messages show that it first attempts reading it with NETCDF before falling back on HDF5, now that you are building GDAL with netcdf_mem.h?

It does not appear so. I'm going to try rebuilding with Even's versions today and see if that helps.
@piyushrpt
Are you seeing results like mine on your end?
@idixon
The last time I tried (when the PR was merged), I was able to use my old proj library and it worked. I need to setup my proj6 before giving this a shot again.
I've just committed in a529c1a a fix needed to detect netcdf_mem.h in recent netcdf versions (tested with 4.6.2). gdalinfo /vsicurl/https://s3.amazonaws.com/idixon/S1-GUNW-D-R-042-tops-20190103_20181210-140759-38619N_36645N-PP-24f6-v2_0_0.nc
is opened with the netcdf driver with this version
Change backported to release/2.4 branch
Everything looks great against NETCDF v4.6.2 now!
ok, closing that issue then
Thank you for the help @rouault and @piyushrpt!
Expected behavior and actual behavior.
Running GDAL against NETCDF-4 groups has different results depending on if the data is local or accessed using vsicurl.
Run locally gdal_translate extracts a geotiff with spatial information however a gdalinfo on the container doesn't appear to return the correct information.
Run over vsicurl it's the opposite problem. A gdalinfo on the container provides verbose information but a gdal_translate appears to be incomplete.
Ideally GDAL should behave the same locally and over vsicurl.
Steps to reproduce the problem.
