The /vsicurl/ limitation isn't important, I just thought it'd be a nice way to brag about GDAL ;-) However, one problem still persists. While I can prod into the decompressed file (e.g. after I have gunzipped it), the following command still reports a problem, e.g: $ gdalinfo /vsigzip/GlobAlbedo.2004001.h17v04.nc.gz ERROR 1: netcdf error #-33 : NetCDF: Not a valid ID . at (netcdfdataset.cpp,~netCDFDataset,1446) gdalinfo failed - unable to open '/vsigzip/GlobAlbedo.2004001.h17v04.nc.gz'. gdalinfo --version GDAL 1.10.0, released 2013/04/24 $ gunzip GlobAlbedo.2004001.h17v04.nc.gz $ gdalinfo GlobAlbedo.2004001.h17v04.nc.gz ERROR 4: `GlobAlbedo.2004001.h17v04.nc.gz' does not exist in the file system, and is not recognised as a supported dataset name. gdalinfo failed - unable to open 'GlobAlbedo.2004001.h17v04.nc.gz'. $ gdalinfo GlobAlbedo.2004001.h17v04.nc Driver: netCDF/Network Common Data Format Files: GlobAlbedo.2004001.h17v04.nc Size is 512, 512 Coordinate System is `' Metadata: NC_GLOBAL#Conventions=CF-1.4 Subdatasets: SUBDATASET_1_NAME=NETCDF:"GlobAlbedo.2004001.h17v04.nc":DHR_VIS SUBDATASET_1_DESC=[1200x1200] DHR_VIS (32-bit floating-point) [....] Thanks!
