    1111If you see level 3 images where "up" is along the flight direction rather than north, this means your viewer hasn't correctly read the georeferencing information.  The most common case is loading the level 3 HDF directly into ENVI.  There is no well defined standard for georeferencing in HDFs so ENVI cannot read the information there and shows data in file order.  To avoid this problem, export the data to a BIL or GeoTIFF file and load that into ENVI instead, e.g.:
    1212{{{
    13  # BIL file (recommended)
     13 # BIL file (recommended), creates .hdr file too
    1414azexhdf -v -h level3_file.hdf -Be level3_file.bil
