Hai,
Jason thanks for your reply
Createcopy method works fine.When i am using create copy method at that
instance only a file is created in the specified path. But the format of the
file is different what i want and another thing is how to get the metadata
information from the source dataset
Vincent,
I'm CC'ing the grass-dev list as gdaldem shares the same formula with the
GRASS r.shaded.relief utility and I also think they are affected (I've only
compared the code, not tested r.shaded.relief, so I could be wrong of course)
I think your analysis is right. To check, I've created an
Oops. Sorry folks. It works after a small bug fix in the algorithm.

I moved my level 1 tiles to a machine with big hard disk, many processors and
a lot of memory.
Then I restarted the process taking the level 1 tiles as source :

Hi,
Perhaps Robert Ramey's notes will be of some interested here.

On possible problem in this particular example is that the ArcInfo ASCII
Grid (AAIGrid) driver does not support the Create method of the GDAL API,
only the CreateCopy method, correct? (Please correct me if I am wrong about
this.) Therefore the procedure for converting IMG to ArcInfo ASCII Grid with

While the docs state "azimuth of the light, in degrees. 0 if it comes
from the top of the raster, 90 from the east, ..." (so: clockwise from
north), I find that a sun azimuth of 0 degrees is west, 90 is sout

I've never used C#, mainly use python, but guess the process will be
similar.
The idea is that you:
1) open your source dataset (the img file)
2) instantiate the arcinfo ascii driver (gdal.GetDriverByName in python
to get a driver instance)
3) use the driver instance to create a new file with th

*Use* the utility.
If you really must do this using C#, do read the documentation and
examples: http://trac.osgeo.org/gdal/wiki/GdalOgrInCsharp
You can skip C# altogether and use batch scripts, powersh

OGR is for vector; GDAL is for raster. And Vajram is working with raster

yeah..
I saw that utility in the fwtools\bin folder.
But it gives some error,when i added the reference to my C# project.
Actually i need to do this task programatically. This class is available in
any other dll
can u tell me please.

Just ran it as an external program. Use Process.Start(), or
WshShellClass, or whatever.
But please, please, run gdal_translate alone to get a feel of how it works.
Don't rush into the code.

You need to download the GDAL utilities, or some bundle that includes
them (such as osgeo4w or fwtools).
Then, open up a console and refer to the documentation:
