Re: [gdal-dev] Understand Why a netCDF4 File Is Not Supported

2022-09-01 Thread Scott Smith via gdal-dev 
Hi Jukka,

Thanks for looking into this. If I understand correctly, this means I will
have to do a little extra work to convert these into a raster-y/geotiff
format other than simply using gdal_translate.

Thanks for pointing me in the right direction!

Hi,

Ogrinfo seems to open the file.

Aihe: [gdal-dev] Understand Why a netCDF4 File Is Not Supported

Hi All,

I am trying to work with some SMOS data, specifically the netCDF4 files from 
https://smos-diss.eo.esa.int/oads/access/.

Running gdalinfo or gdal_translate using the Docker image 
osgeo/gdal:ubuntu-full-latest on these netCDF4 files seems to fail with

ERROR 4: '' not recognized as a supported file format.

Full command and output

docker run -v /local/directory/containing/file/:/mnt/data/ 
osgeo/gdal:ubuntu-full-latest gdalinfo --debug ON 
/mnt/data/SM_OPER_MIR_SMUDP2_20220101T001713_20220101T011034_700_001_1.nc

>From this I'm not really able to understand what is wrong with the file.

The file with which I am testing is available here: 
https://drive.google.com/file/d/1r4R2gy0w2nyEv1fwmMNNR8CHhwjvayIk/view?usp=sharing

I am trying to figure out what is "wrong" with these files which render them 
unreadable by gdal. I have not managed to find much by Googling. I'm happy to 
continue investigating if anyone is happy to provide any pointers to where I 
should be looking.

Any advice, pointers or help would be greatly appreciated.

Many Thanks

p.s. I'm not sure if this is relevant or helpful, but I have managed to have 
some partial success with an older version of gdal and some "single variable" 
files I created from the original. Included for information, the gdal version 
is   GDAL 3.3.2, released 2021/09/01   and a file which worked with gdalinfo is 
https://drive.google.com/file/d/1r4R2gy0w2nyEv1fwmMNNR8CHhwjvayIk/view?usp=sharing
