[FWTools] gdal_translate

[Trent M Hare]

Naresh,
        You might take a look at an application, called Mirone, that is an 
excellent marriage of Matlab, GDAL (and GMT). You may not need to covert 
to tiff and just the ESRI Grid directly for Matlab. 
http://w3.ualg.pt/~jluis/mirone/

For your issue, make sure you are points at the correct *.adf file. e.g.
>gdal_translate hrus1\w001001.adf out.tif
which worked for me.

Regards,
Trent

And you file looks fine as shown by gdalinfo

Hello,
  I am developing a geospatial tool in matlab. While running this tool, 
the user will have access to a grid file developed by ArcGIS ( *.adf) 
developed from another program. However, since I am developing the tool in 
Matlab (which can read geotiff), I need to convert the .adf file to .tif 
file.
   One of the methods I am considering is to use the gdal_translate 
function. I downloaded the FWTools (2.4.2) and to start with, I used the 
OpenEV program to open the .aux file attached with the *.adf file. However 
when I tried to export using (File -> export), I get an error message 
saying that it is unable to create this tif file.
   Eventually I would like to fire up the gdal_translate.exe from within 
Matlab to convert the grid to tif. I have uploaded the grid file to the 
following link.

I would appreciate any suggestions/comments as I troubleshoot this 
problem.
 
Thank you.
Naresh
