Hi,<br><br>Does anyone know if Gdal, current version or development version, is able to translate from Geostationnary projection to other regular projection ?<br><br>Is it planned in future Gdal release ?<br><br>Many thanks !<br>

Hi Stéphane<br>
<br>
According to <a href="http://www.gdal.org/gdal_translate.html" target="_blank">http://www.gdal.org/gdal_translate.html</a><br>
<br>
*-a_ullr* /ulx uly lrx lry/:<br>
Assign/override the georeferenced bounds of the output file. This<br>
assigns georeferenced bounds to the output file, ignoring what would<br>
have been derived from the source file. <br>
Yes... Regarding extracting sub-domains, I didn't tried<br>
<br>
Yes, please keep me in touch in case there are better methods<br>
<br>

Thanks for feedback !<br>
<br>
Do you have any ideas of the meaning of -a_ullr arguments they gave you ?<br>
<br>
Futhermore, once you get your GeoTiff file, did you success to translate it to other projection, or extracting sub domains ?<br>
<br>
I've heard that GEOS projection is not so really supported currently by GDAL, and re-projection / sub domain extraction doesn't work correctly ...<br>
<br>
I'll keep you in touch if any news !<br>

Greetings<br>
<br>
I had exacly the same problem. I have been using LSASAF data (from<br>
MSG-2nd Generation satellites) that provides LST and FVC in HDF5<br>
files. For some technical reason they are not goerreferenced and<br>
their information.<br>
<br>
I talked with a few ILWIS software developers and they gave the<br>
following Commands (adapted to my spatial coverage images):<br>
<br>
gdal_translate -a_srs "+proj=geos +lon_0=0.0 +h=35785831 +x_0=0.0<br>
+y_0=0.0" -a_ullr -924124.2 5421728.5 4179561.6 3468466.1<br>
"HDF5:"HDF5_LSASAF_MSG_LST_Euro_200802170100"://LST"<br>
"euro_area_georeferenced.tif"<br>
<br>
<br>
gdalwarp -s_srs "+proj=geos +lon_0=0.0 +h=35785831 +x_0=0.0<br>
+y_0=0.0" -t_srs "+proj=latlong" "euro_area_georeferenced.tif"<br>
"euro_area_latlong.tif"<br>
<br>
My HDF5 file doesn't contain any infoprmation regarding GEOS<br>
projection. So, I had to do this<br>
<br>
<br>
Hope this helps<br>
<br>
If you get any news/information/method regarding this, please let<br>
me know<br>
<br>
Best regards<br>
Antonio<br>
