NETCDF gets the geotransform (from x_grid,y_grid which report in the metadata) but no crs: gdalinfo NETCDF:ATL20-02_20181001010615_00370101_004_01.h5 -sd 1 -nomd Driver: netCDF/Network Common Data Format Files: ATL20-02_20181001010615_00370101_004_01.h5 Size is 316, 332 Origin = (-3950000.000000000000000,4350000.000000000000000) Pixel Size = (25000.000000000000000,-25000.000000000000000) Corner Coordinates: Upper Left (-3950000.000, 4350000.000) Lower Left (-3950000.000,-3950000.000) Upper Right ( 3950000.000, 4350000.000) Lower Right ( 3950000.000,-3950000.000) Center ( 0.000, 200000.000) Band 1 Block=500x500 Type=Float64, ColorInterp=Undefined Unit Type: degrees_north HDF5 doesn't get geotransform or crs: gdalinfo ATL20-02_20181001010615_00370101_004_01.h5 -sd 1 -nomd Driver: HDF5Image/HDF5 Dataset Files: ATL20-02_20181001010615_00370101_004_01.h5 Size is 316, 332 Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 332.0) Upper Right ( 316.0, 0.0) Lower Right ( 316.0, 332.0) Center ( 158.0, 166.0) Band 1 Block=500x500 Type=Float32, ColorInterp=Undefined NoData Value=3.4028235e+38 This is unproblematically NSIDC 25km south, there's no mix of poles in this one. I honestly don't know what to expect from these files generally though I get my hopes up sometimes haha. I'll have to keep notes and explore more deeply with native HDF5 tools.
