[gdal-dev] vsicurl access to a netcdf file does not see the coordinates

[Joaquim Manuel Freire Luís]

Hi,

GDAL master here

When I run gdalinfo on a remote nc file, instead of reporting the coordinates it prints the array size

gdalinfo /vsicurl/http://w3.ualg.pt/~jluis/ftp/tmp/idades_v2012.grd
Driver: HDF5Image/HDF5 Dataset
Files: none associated
Size is 2029, 1168
Metadata:
  Conventions=COARDS
  description=File written from Matlab
  node_offset=0
  Source_Software=Mirone
  title=Grid computed inside Mirone
  _nc3_strict=1
Corner Coordinates:
Upper Left  (    0.0,    0.0)
Lower Left  (    0.0, 1168.0)
Upper Right ( 2029.0,    0.0)
Lower Right ( 2029.0, 1168.0)
Center      ( 1014.5,  584.0)
Band 1 Block=1015x584 Type=Float32, ColorInterp=Undefined
  NoData Value=nan
  Metadata:
    z_actual_range=-0.0558451935648918 181.299896240234
    z_long_name=z
    z_units=unknown
    z__FillValue=-nan(ind)


However, if I download the file and run it locally, then the result is correct
