[GRASSLIST:6258] hdf and modis/aster

Hi all, I am trying to import some MASTER data (combined MODIS and
ASTER) that is an hdf4 file (it should have the same exact format as
MODIS data). After realizing that I need to import the subdatasets
(which import fine into an XY location), I have run into a problem. It
seems that the data I want is in one subdataset, but the latitudes and
longitudes are in separate subdatasets. How can I import this so that
the data I want is actually georeferenced?

I tried gdal_translate on a whim (gdal_translate -of GTiff -b 1
subdataset myfile.tif), but I ended up with a geotiff that either gives
me an error of "cellhd.proj = 0 (unreferenced)" or if r.in.gdal -o
"G_set_window(): Illegal latitude for South".

Anyone run into this before?

Thanks,
Ian

I've not imported hdf4 directly, but used the MODIS reprojection tool to tile and convert the data GeoTiff. Then importing it into GRASS was a breeze.

What does gdalinfo say about your hdf4 file? I've had an issue that hdf4 "Aster relative DEM" was not recongnized as georeferenced in newer Gdal
versions due to changes in the hdf driver. Maybe that is your case too?

Anybody correct me if I'm wrong, but it seems that gdalinfo doesn't recognize any info about the georefercing in your hdf - see "Coordinate System is `'".
This is likely the reason of your problems. Either your file is not georeferenced or there is something wrong with the hdf driver in gdal. Dig the gdal mailing list and bugtracker for relevant info and consider bugging gdal developers if needed then.

Hi all, I am trying to import some MASTER data (combined MODIS and

According to the gdal maintainer (a few months back), there are problems
with the GCP and related data in Modis hdf files. So you can't use gdalwarp
to georeference them. The georeferenceing data in Terra ASTER hdf files is
OK. My r.in.aster script will georeference and import these data.

Here is the full output of gdalinfo. Bit long, but I think it looks
normal (I don't have a ton of experience with these files yet).

What does gdalinfo say about your hdf4 file? I've had an issue that
hdf4 "Aster relative DEM" was not recongnized as georeferenced in
newer Gdal
versions due to changes in the hdf driver. Maybe that is your case too?

Hi all, I am trying to import some MASTER data (combined MODIS and
ASTER) that is an hdf4 file (it should have the same exact format as
MODIS data). After realizing that I need to import the subdatasets
(which import fine into an XY location), I have run into a problem. It
seems that the data I want is in one subdataset, but the latitudes and
longitudes are in separate subdatasets. How can I import this so that
the data I want is actually georeferenced?

I tried gdal_translate on a whim (gdal_translate -of GTiff -b 1
subdataset myfile.tif), but I ended up with a geotiff that either
gives
me an error of "cellhd.proj = 0 (unreferenced)" or if r.in.gdal -o
"G_set_window(): Illegal latitude for South".

Anyone run into this before?

Thanks,
Ian

According to the gdal maintainer (a few months back), there are problems
with the GCP and related data in Modis hdf files. So you can't use gdalwarp
to georeference them. The georeferenceing data in Terra ASTER hdf files is
OK.

Right. Fortunatelly they are taking care of this:
