[gdal-dev] another problem HDF5

[Michael Sumner]

This time, with:

https://n5eil01u.ecs.nsidc.org/ATLAS/ATL20.004/2018.10.14/ATL20-01_20181001010615_00370101_004_01.h5

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.

Cheers, Mike
