Hello,
I want to reproject MODIS higher order reflectance/emissivity data to
UTM coordinates using IDL. I got the white paper for the MODIS TOOL.
My problem is that the UTM zone is different depending on the grid
values h09v05,h10v05, etc. Should I use FOR loop, or CASE, or WHERE
routines?
Here is the file names.
MOD43B4.A2000049.h09v05.004.2002357024540.hdf
MOD43B4.A2000049.h10v05.004.2002357034015.hdf
MOD43B4.A2000193.h08v05.004.2003043002112.hdf
MOD43B4.A2000353.h08v04.004.2003077055209.hdf
MOD43B4.A2000353.h09v04.004.2003077070335.hdf
....
Thanks

Hello All,
Finally, I accepted MCRT from ITTVIS, the Modis COnversion Tool works
fine this.
Thanks

Actually, you don't even need perl for the MRT. A plain old shell
script works fine. If the original poster really needs this to be
part of some larger IDL program, then they can just call the MRT using
spawn.

You could try the MODIS Conversion Toolkit, which can handle single
and batch mode processing of all known products. It's an ENVI
plugin. You can download it here: http://www.ittvis.com/UserCommunity/CodeLibrary.aspx.
Search for "MODIS" and you'll find it.

I am working on at least 1000 images. I think I stick to IDL. Is there
any constructive suggestion? :-)
Thanks

But, I have to process at least 1000 images. That tool handles one by
one.
Any other constructive advice? :-)
Thanks

I don't think IDL is the right tool for this task. Have you tried the
MODIS Reprojection Tool?
http://lpdaac.usgs.gov/landdaac/tools/modis/
It is free, and it handles all the gridded MODIS Land products.
Cheers,
Liam.
