Hi all, Reopening an old thread, to know if any new knowledge has been acquired about the MODIS v005 SIN->LatLong reprojection in GDAL, within our GRASS perspective.
I may have time to look into it in a future project, but would not want to discover somebody went over it already... Thank you, Yann ________________________________________ From: [email protected] [[email protected]] on behalf of Markus Neteler [[email protected]] Sent: Tuesday, October 04, 2011 1:38 PM To: Chemin, Yann (IWMI) Cc: GRASS user list Subject: Re: [GRASS-user] download MODIS data (MOD43B3) On Tue, Oct 4, 2011 at 9:23 AM, Chemin, Yann (IWMI) <[email protected]> wrote: > It asks for pyMRT...

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.
