Hi Julien,

I would very interested in trying your netCDF patches. The new OceanColor L2 format completely broke up my (Mirone) working flow.

Also regarding https://trac.osgeo.org/gdal/ticket/5291 sorry if I didn't understand, is there anything I can do to help?

Thanks

Joaquim


Hi,

Note that I have implemented in GDAL support of NetCDF-4 files including groups and support of warping new NASA OceanColor L2 format using geolocation array but unfortunately still not finalized the patch to GDAL... More details here: http://osgeo-org.1560.x6.nabble.com/gdal-dev-NetCDF-driver-improvements-including-groups-support-td5185773.html
This also works for VIIRS L2 products.
I can provide the patch to you if you are interested, let me know.

Regards,
Julien

Hi!

The format of the new OBPG OceanColor files is HDF5 (aka NetCDF4), so you should have your GDAL compiled with HDF5 support:
http://www.gdal.org/frmt_hdf5.html

Then you can access the content of the file using groups and variables
syntax:
gdalinfo HDF5:"A2015069035500.L2_LAC_OC.nc"://geophysical_data/chlor_a

Regards!
Anton

I am using windows 7(32-bit) and want to warp NetCDF (nc) files and
save the output as GeoTIFF.

First I run gdalinfo first to get the info of the subdataset I need
and added NeTCDF in the beginning(e.g. gdalinfo
NETCDF:"A2015069035500.L2_LAC_OC.nc") but was unfortunate because a
warning
appeared:

Warning 1: Variable has 0 dimension(s) - not supported.
gdalinfo failed - unable to open 'netCDF:A2015069035500.L2_LAC_OC.nc'.

Command line input:

gdalinfo A2015069035500.L2_LAC_OC.nc


NetCDF is present when I tried `gdalinfo --formats`.

Does anyone have any idea about this?
