Thanks for your reply andrea.

I had gone through the code but still I couldn't understand how to find
calculate bounding box which covers all mosaic images.  Also please tell
me how to merge the images in terms of envelope calculation for
resulting image.

Please give any idea for my problem.

Anyways, there has been some work on this area already, see:
http://jira.codehaus.org/browse/GEOT-2905

We're looking into integrating it, but it's not easy since
none of the developers have a use for GeoRaster as of today,
so it's difficult to find the time to test the code, avoid
any direct dependency to the Oracle specific API so that it
builds even without the Oracle jars (since there
are redistribution issues with the license of those jars)
and so on.

But it may work well for you as it is

Cheers
Andrea
