Dear Kenlo, Dear All
If do you not be afraid to go dertours, try to translate the hdf-eos files
into arc/info ascii grids using  the  EOSGIS DATA TRANSLATOR (egnt) (a free
program from the MODIS/DAAC server). Please have in mind that MODIS data are
not always in the hdf-eos format, native hdf4 is also used for some
products. I use actually mapped MODIS AQUA oceal L3 data, translate them
with the attached egnt program into ascii grids and import them into grass
using r.in.arc. I thing, your MODIS file are land data; you can use the
modis reprojection tool to manipulate the data and translate them into
anscii-grids: http://edc.usgs.gov/programs/sddm/modisdist/index.shtml The
reprojection tool is fot land data only. I am sorry that r.in.hdf does not
work. Please let me know, if you have other ideas.
Cheers, Jan

Subject: [GRASSLIST:5564] r.in.hdf


Dear GRASS users:

I would like to ask your help.
I have troubles using r.in.hdf in GRASS5.0.1 and GRASS4.3
on Linux on my intel-PC.

On GRASS5.0.1 I found r.in.hdf had not been installed,
hence I tried to install it by myself by running "# gmake5"
under ~/grass5.0.1/src.garden/grass.hdf/ but I came up with
some error messages like this:

  No rule to make target "-lgis" which is necessary for
  ~/grass5.0.1/dist.i686-pc-linux-gnu/etc/bin/cmd/r.in.hdf.
  Stopped.

(To tell the truth, this may not be very accurate because I
translated it from the original error message in Japanese
in my Linux system).
I found in the past logfiles of the GRASS mailing-list that
ftp://www.geog.uni-hannover.de/incoming/grass.hdf.tar.gz
may solve this problem (thanks to Mr. Neteler) but unfortunately
the ftp server did not respond.

On GRASS4.3, I downloaded a precompiled binary and found that
r.in.hdf was one of default commands already compiled in the
binary. I tried to use it for two HDF files: a SPOT-Vegetation
radiometric data as well as MODIS data (MOD02QKM), but in both
case, I came up with messages as follows and obtained no data in
raster data lists at g.list.

  Large file - reading row by row.
  Writing GRASS output file: hdf.rast01
  WARNING: G_set_window(): Illegal latitude for North

I know the HDF format of MODIS is not pure HDF but HDF-EOS and
I guessed this "dialect" in HDF might caused this problem, but
I do not know any possible problems with SPOT-Vegetation.

As long as I tried, other basic functions of GRASS4.3 and
GRASS5.0.1 seem to be working on my system.

I appreciate any comments concerning to these troubles.
