To view the raster data loaded into the database, you can use GeoRaster viewer. We are interested in the Georaster folder. Because the geometry can sometimes be invalid, the spatial index can be incorrect and return incorrect data to the spatial operators. If you check DE9-IM coincidence between geometry objects, take into consideration the setting of the GeometryRelationships property. If you want to use the Java loader, you need to download the database examples from Oracle site. The join requires that a column with the name ‘IndexColumn’ exists in the view.
