Hi, I can remember working with Baskar. I hope your extension is a subclass of the JDBCAccessCustom base class, otherwise we would have an additional architecture (We have already two, one based on files maintained by Simone, the second based on jdbc, maintained by me). The current Oracle Georaster plugin is an implementation of
http://docs.codehaus.org/display/GEOTDOC/Customized+JDBC+Access+for+images If I got it right, you calculate the mosaic on the fly, what about pyramid building ?. About the test case. There is already an OracleGeoraster test, I think it would be a good idea to use this test as a template. If I am right, you only have to modify the import of the images. Anyway, your approach is very interesting for me because I intend to add postgis wkt raster which has a database layout similar to yours. And last not least, do you plan to extend the import utility. The current Oracle Georaster implementation can use the original Oracle tools for import, postgis wkt raster has its own tool and for the rest I wrote the import utility based on the output of gdal_retile.
