Hello, I use the ImageMosaicJDBC plugin to connect to raster data stored in an oracle DB and WMS to visualize it. For my test I used the original BBOX and height/width of the GeoTIFF image, so no interpolation should be necessary (nevertheless I tried all 3). I compared the result with a WMS request based on the image stored in the file system. When I zoom in the pixels are clearly different, it looks like the resolution is a bit lower with ImageMosaicJDBC and shifted too.
I also used WCS to confirm that the image is stored without any information loss in the oracle database. .) WMS request with GeoTIFF in file system <http://osgeo-org.1560.x6.nabble.com/file/n5262463/file.png> --> identical with original GeoTIFF .) WMS request with GeoTIFF in oracle with ImageMosaicJDBC plugin <http://osgeo-org.1560.x6.nabble.com/file/n5262463/plugin.png> --> Quite different to the original GeoTIFF .) WCS request with GeoTIFF in oracle --> I get the original GeoTIFF so the image is correctly stored in the database Does anyone know why ImageMosaicJDBC returns a different image, although epsg code, bbox, widh, height are exactly the same?
