Greetings
I'm a GRASS user and I'm dealing with some difficulties with HDF5
import/translate. I'm using gdal_translate to import HDF5 files to GRASS but
I need to use GCP's information and coordinate system. My question is, using
GDAL tools how can I import/use GCP and coordinate systems that are
Pedro,
You need to specify the individual subdataset of the hdf5 file to retrieve
the metadata. This page, http://www.gdal.org/frmt_hdf5.html , shows a way to
do it in gdalinfo. GRASS should be in similar lines.

Hi
I have specified individual subdataset and I have run gdalinfo but it only
writes in the terminal window it doesn't store in a specific file to be
read.
As it says in that link: This driver is intended only for importing remote
sensing and geospatial datasets in form of raster image. There is n

Here a script how things could be done (contains some MODIS specialities):

Petro,
yes it is not surprising there's nothing specific in the doc of the HDF5
driver about what to do with GCPs as quite a few other drivers can also
return GCPs. You're probably interested by a generic tool such as gdalwarp to
rectify the image from the GCPs : see http://gdal.org/gdalwarp.ht
I'm trying to geo-reference a .tif image, but the
corner coordinates don't change. I used gimp to get the
pixel and lat/lng of 4 points on the image. I converted
the lat/lng to the desired coordinates, then used this
command:
gdal_translate \
-a_srs epsg:3395 \
-gcp 1954 1085 -8682920.28
Hello, i am new to using GDAL, from what I've looked into it seems great. I
am using pythonwin to interact with GDAL.
For installation, I followed the instructions here:

manually). All my windows system variables are identi

gdal_translate is an executable program. You can use it directly from the
command line. Refer to http://www.gdal.org/gdal_utilities.html for python
scripts and other programs. Python scripts are indicated by .py extension.

hi Chaitanya,
Thanks for the response. Perhaps i am just not understanding or remembering
terms, but is the pythonwin interactive window not the command line? that is
where i am trying to access gdal_translate (i guess run the exe would be
more corrent), yet it completely does not recognize the
ytrapaet,
pythonwin is for python's commands. gdal_translate.exe is a seperate
executable file. You need to run it from the system's command line (Start ->
Run -> cmd). If your environment variables are set as described in the
document you should be able to run it from your command prompt.

What do I need to do to get the output file to have the
correct coordinate system?
Hello Wendell,
You have to use gdalwarp :
gdalwarp -r lanczos bw_ref.tif bw.tif
Alternatively, you
Chaitanya - thank you! i am not used to much GIS programming outside of the
pythonwin context. Im glad its not a setup problem.
I'm not sure i need to make some more changes to my environment that are not
mentioned in that pdf article describing the setup GDAL; every time i try
any sort of comman
hello,
our system reads a large amount of images and used LIBTIFF directly.
to quicken things up we implemented prefetching of whole images which
resided on a different OS-thread.
we moved to GDAL for better format support and now the prefetching mechanism
isn't helpful anymore.
actually now it is
