Christian, As per your statements below, it seems that at this time the functionality Baskar is working on for this purpose is not yet justified for inclusion in the GeoTools libraries themselves but we intend to keep working on this functionality and appreciate your guidance thus far.
We need to look further into the mosaicing of rows in the Oracle GeoRaster table so we can validate or invalidate this use case. We are doing in fact what you state should not work, that is pyramiding each row in the table separately but making sure to create the same number of pyramid levels for each row, then mosaicing those rows together at runtime so we can more easily manage the raster and replace pieces of the raster, but making them logically appear to be one large raster. Despite the fact that we are not ready for inclusion, we would still like to see the developer agreement so we can determine if we should have these in place anyway. Thanks again, Bruce -----Original Message----- From: christian.muel...@nvoe.at [mailto:christian.muel...@nvoe.at] Sent: Thursday, May 13, 2010 1:21 AM To: Baskar, Dhanapal Cc: geotools-devel@lists.sourceforge.net Subject: Re: [Geotools-devel] Proposed Mosaicing GeoRaster Module Hi Baskar, it looks like you want to denote your code to geotools. I am not sure about that. What we can do in any case, we could attach your code as an example to the documentation. This would be nice. I assume your customer has allowed you to publish your code. @Andrea, any legal problems if we add the code as an example to the wiki ? The other possibility is to really integrate your code into geotools. If you like to do that, there are some additional things to check. 1) I think your db layout is using one table to store the tiles. Do you create pyramids for each tile ?. If this is the case, then we can stop here since pyramids have to be built from the whole image, otherwise it is not correct. The correct way would be to create the pyramids yourself and store them in different tables or add an db attribute "pyramidlevel" to the db table. Btw, this is the way how to do it with postgis wkt raster. 2) If we can clarify 1) , you have to add Online Tests, see H2CustomTest and GeorasterOnlineTest as an example. I have to check against Orcale 10.2 3) You must sign a developer agreement (I do not know the exact name for this paper).
