Hi,
I am currently using GDAL 3.1.3 on a Ubuntu machine. I am trying to work with
NetCDF files using the UGRID convention (described here:
https://ugrid-conventions.github.io/ugrid-conventions/).
I am having difficulty working with this kind of NetCDF file. Here is the
output of `gdalinfo` against one subdataset of a NetCDF file using the UGRID
convention.
`$ gdalinfo -mm -proj4
NETCDF:"PATH_TO_NETCDF/CMC_shop_slfeav200n_surface_sfc_0_2019080706_P040.nc":St_Lawrence_River_face_nodes
Warning 1: No UNIDATA NC_GLOBAL:Conventions attribute
Driver: netCDF/Network Common Data Format
Files: PATH_TO_NETCDF/CMC_shop_slfeav200n_surface_sfc_0_2019080706_P040.nc
Size is 3, 87396
Metadata:
St_Lawrence_River_face_nodes#cf_role=face_node_connectivity
St_Lawrence_River_face_nodes#long_name=Maps every triangular face to its
three corner nodes.
St_Lawrence_River_face_nodes#start_index=0
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0,87396.0)
Upper Right ( 3.0, 0.0)
Lower Right ( 3.0,87396.0)
Center ( 1.5,43698.0)
Band 1 Block=3x1 Type=Int32, ColorInterp=Undefined
Computed Min/Max=0.000,53331.000
NoData Value=-2147483647
Metadata:
cf_role=face_node_connectivity
long_name=Maps every triangular face to its three corner nodes.
NETCDF_VARNAME=St_Lawrence_River_face_nodes
start_index=0
`
Following this output, I can confirm that the size and the extent (Corner
Coordinates) are not right for example.
Is there anyone who has worked with NetCDF files using the UGRID convention? Is
GDAL capable of handling or manipulating this kind of NetCDF file?
Thanks a lot in advance for your answer(s)!
