Hey all, I really have great confusion on how to convert my HDF 4 images
which reside as multiple bands into a single HDF file to a GeoTiff
geo-referenced image. In reality, I need to convert the format into a single
latitude/longitude *WGS-84* referenced TIFF image..I need to do this and at
the same time obtain a .tfw file which specifies the top left corner
coordinates of the image's bounding box and the pixel resolution of the
image.
I've tried to run the gdalinfo command on one of my images.. The image name
is AMOD021KM20061229043102.hdf and when I run the command (under Ubuntu) I
get the following stack report (the subdatasets are at the bottom part):

It looks like the subdatasets could be malformed... This is because I get
these SUBDATASET_X_NAME=HDF4_SDS:UNKNOWN: syntax.. is that right.. I've been
told that the images are MODIS images from Terra and Aqua satellites. I also
read that MODIS is used for snow detection only.. is this correct??
I'm trying to understand how to achieve what I need and so far I understand
that the required commands are the gdal_transform or the gdalwarp commands.
When I run gdal_translate on the file, I get the following:
rasdaman at mattia-desktop:~/FTPCHINA$ gdal_translate
AMOD021KM20061229043102.hdf test.tiff
Input file contains subdatasets. Please, select one of them for reading.
rasdaman at mattia-desktop:~/FTPCHINA$
Hence my question is, how do I tell the command to pick up a certain
dataset?? And, where can I find the relative documentation for this command
when applied to multiple HDF bands??
Finally, I reside in Germany and need to transform a whole lot of images
into GeoTiff to later establish a WMS service .. Hence all conversion will
need be done remotely... Does anyone have any suggestions on how I should go
on about this?? Should I be using the gdal library or would I best bet on
something else???
Msphinx?? ENVI??
