"""The VIIRS EDR FLOOD reader operates on HDF4 files.

Files usually have the following naming scheme:

    WATER_VIIRS_Prj_SVI_{platform_shortname}_d{start_time:%Y%m%d_t%H%M%S%f}_e{end_time:%H%M%S%f}_b{orbit:5d}_{source:8s}_{dim0}_{dim1}_01.hdf
    or
    WATER_VIIRS_Prj_SVI_{platform_shortname}_d{start_time:%Y%m%d_t%H%M%S%f}_e{end_time:%H%M%S%f}_b{orbit:5d}_{source:8s}_{aoi:3s}_{dim0}_{dim1}_01.hdf

This reader's default resampling algorithm is ``nearest`` for Nearest Neighbor resampling.
The ``--remap_method`` parameter is set to ``nearest``.
