[gdal-dev] read envisat with gdal

[Roger André]

Downloaded a sample file from
http://envisat.esa.int/services/sample_products/aatsr/L2/.  Seems to work
fine in Python.

$ python
>>> from osgeo import gdal
>>> image =
gdal.Open('ATS_MET_2PNETB20020729_070738_000058362008_00092_02150_0873.N1')
>>> image.GetMetadata()
{'MPH_STATE_VECTOR_TIME': '29-JUL-2002 08:14:40.282674', <snip>}
>>> metadata = image.GetMetadata()
>>> metadata['SPH_FIRST_MID_LAT']
'+0058766642'
>>> image.GetMetadataItem('SPH_FIRST_MID_LAT')
'+0058766642'

Can you run gdalinfo on your file and post the output?

Thanks,

Roger
