Hi there,
I am using this one right now on Level 2 and 3 MODIS products

maybe of help,

Note that, when you are using modis sinusoidal projected hdf products,
you might have to use something like this to prevent a shift in the y
direction which becomes more pronounced when further from the equator:
gdalwarp -s_srs '+proj=sinu +R=6371007.181 +nadgri...@null +wktext'
-t_srs EPSG:4326 <hdf> <out.tif>
to force gdalwarp to adjust for the custom ellipsoid that the modis
sinusoidal projection uses. Or, at least, I had to some time ago. It
might have been 'fixed' already.

Hi list,
I am trying to convert MODIS .hdf files to .tif files (it worked with
ASTER files earlier, thats why I am now really curious).
i typed
gdalinfo MOD021KM.A2008134.1935.005.2009071201911.hdf
result:
......
SUBDATASET_1_NAME=HDF4_EOS:EOS_SWATH:"MOD021KM.A2008134.1935.005.2009071201911.hdf":MODIS_SWATH_Type_L1B:EV_1KM_RefSB
SUBDATASET_1_DESC=[15x2030x1354] EV_1KM_RefSB (16-bit unsigned integer)
SUBDATASET_2_NAME=HDF4_EOS:EOS_SWATH:"MOD021KM.A2008134.1935.005.2009071201911.hdf":MODIS_SWATH_Type_L1B:EV_1KM_RefSB_Uncert_Indexes
SUBDATASET_2_DESC=
........
then:
gdalwarp
HDF4_EOS:EOS_SWATH:"MOD021KM.A2008134.1935.005.2009071201911.hdf":MODIS_SWATH_Type_L1B:EV_1KM_RefSB
modis.tif
Have you any ideas, what is the problem?
Thanks,
Anja
