[GRASS-user] download MODIS data (MOD43B3)

[Chemin, Yann (IWMI)]

I will try to reach that computer soon and get back on that with the full error message...
I used SVN trunk on an Ubuntu machine. 
Wish I could take time off to figure this GDAL thingy out...

more later,
Yann

I would really need the error message since there is no trace of
a "pyMRT" error message in r.modis.*

Perhaps you mean pyModis? This is part of the module set.

I was in contact with Gail Schmidt (MRT developer) from NASA about this
years ago (MODIS V003 and V004 when MODIS was still in ISIN, I posted
that to gdal-dev some years ago but didn't gain much attention ...
For ISIN (nowadays MODIS is in SIN), the source code is here:
mrt4.1/MRT/resample/calc_isin_shift.c

I am not sure about any potential projection shifts in SIN (MODIS V005),
but the source code of MRT is available if anyone wants to investigate.
Or run comparative test cases in different parts of the world....

For r.modis.* we decided to take the secure route and used MRT.
