[Geoserver-devel] Mosaicing Georaster

Hi,

I am planning to write code for mosaicing oracle spatial Georaster data. I
know how to retrieve and manipulate single georaster. But I am not getting
any idea on how to handle mosaic georaster. Please share any idea on
following.

1. How to calculate envelop for mosaci georaster data from database?
2. Steps to retrive and merge georaster data based on the envelope provided.

Please share atleast any over all idea on how to do this.

cheers,
baskar

You should subscribe to mailing list before sending mails.
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

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.
